FIS and Databricks worked together to develop a conversational analytics system using Spark and machine learning. Their initial approach using pre-trained NLP models had problems, so they built an LSTM model trained on conversation data to predict sentiment. A random forest classifier using the LSTM output and other features achieved 80% accuracy. The full pipeline was deployed on Databricks to continuously learn from streaming conversation data and provide sentiment analysis at scale.

"Lessons learned using Apache Spark for self-service data prep in SaaS world"
Slide deck for the presentation we delivered at Spark+AI Summit 2019 in San Francisco.
In this talk, we will share how we benefited from using Apache Spark to build Workday's new analytics product, as well as some of the challenges we faced along the way. Workday Prism Analytics was launched in September 2017 and went from zero to one hundred enterprise customers in under 15 months. Leveraging innovative technologies from Platfora acquisition gave us a jump-start, but it still required a considerable engineering effort to integrate with Workday ecosystem. We enhanced workflows, added new functionalities and transformed Hadoop-based on-premises engines to run on Workday cloud. All of this would not have been possible without Spark, to which we migrated most of earlier MapReduce code. This enabled us to shorten time to market while adding advanced functionality with high performance and rock-solid reliability. One of the key components of our product is Self-Service Data Prep. Powerful and intuitive UI empowers users to create ETL-like pipelines, blending Workday and external data, while providing immediate feedback by re-executing the pipelines on sampled data. Behind the scenes, we compile these pipelines into plans to be executed by Spark SQL, taking advantage of the years of work done by the open source community to improve the engine's query optimizer and physical execution. We will outline the high-level implementation of product features, mapping logical models and sub-systems, adding new data types on top of Spark, and using caches effectively and securely, in multiple Spark clusters running under YARN, while sharing HDFS resources. We will also describe several real-life war stories, caused by customers stretching the product boundaries in complexity and performance.
Accelerating Machine Learning on Databricks Runtime
"We all know the unprecedented potential impact for Machine Learning. But how do you take advantage of the myriad of data and ML tools now available? How do you streamline processes, speed up discovery, share knowledge, and scale up implementations for real-life scenarios?
In this talk, we'll cover some of the latest innovations brought into the Databricks Unified Analytics Platform for Machine Learning. In particular we will show you how to:
- Get started quickly using the Databricks Runtime for Machine Learning, that provides pre-configured Databricks clusters including the most popular ML frameworks and libraries, Conda support, performance optimizations, and more.
- Get started with most popular Deep Learning frameworks within a few minutes and go deep with state of the art model DL diagnostics tools.
- Scale up Deep Learning training workloads from a single machine to large clusters for the most demanding applications using the new HorovodRunner with ease.
- How all of these ML frameworks get exposed to large and distributed data using Databricks Runtime for Machine Learning."
Using Spark Mllib Models in a Production Training and Serving Platform: Exper...
Overview Uber's Michelangelo is a machine learning platform that supports training and serving thousands of models in production. Most Michelangelo customer models are based on Spark Mllib. In this talk, we will describe Michelangelo's experiences with and evolving use of Spark Mllib, particularly in the areas of model persistence and online serving. Extended Description Michelangelo [https://eng.uber.com/michelangelo/] was originally developed to support scalable machine learning for production models. Its end-to-end support for scheduled Spark-based data ingestion and model training, along with model evaluation and deployment for batch and online model serving, has gained wide acceptance across Uber. More recently, Michelangelo is evolving to handle more use cases, including evaluating and serving models trained outside of core Michelangelo, e.g., on a distributed tensorflow platform providing Horovod [https://eng.uber.com/horovod/] or using PySpark in a Jupyter notebook on Data Science Workbench [https://eng.uber.com/dsw/] To support evaluation and serving of models trained outside of Michelangelo, Michelangelo's use of Spark Mllib needed updating, to generalize its mechanisms for model persistence and online serving. In this talk, we will describe these mechanisms and explore possible avenues for open-sourcing them.

Predicting Influence and Communities Using Graph Algorithms
Relationships are one of the most predictive indicators of behavior and preferences. Communities detection based on relationships is a powerful tool for inferring similar preferences in peer groups, anticipating future behavior, estimating group resiliency, finding hierarchies, and preparing data for other analysis. Centrality measures based on relationships identify the most important items in a network and help us understand group dynamics such as influence, accessibility, the speed at which things spread, and bridges between groups. Data scientists use graph algorithms to identify groups and estimate important entities based on their interactions. In this session, we'll cover the common uses of community detection and centrality measures and how some of the iconic graph algorithms compute values. We'll show examples of how to run community detection and centrality algorithms in Apache Spark including using the AggregateMessages function to add your own algorithms. You'll learn best practices and tips for tricky situations. For those that want to run graph algorithms in a graph platform, we'll also illustrate a few examples in Neo4j. Some of the Community Detection Algorithms included: * Triangle Count and Clustering Coefficient to estimate network cohesiveness * Strongly Connected Components and Connected Components to find clusters * Label Propagation to quickly infer groups and data cleans with semi-supervised learning * Louvain Modularity to uncover at group hierarchies Balanced Triad to identify unstable groups * PageRank to reveal influencers * Betweenness Centrality to predict bottlenecks and bridges.

Enterprise Data Governance and Compliance at Scale with Sri Eshasubbiah and S...
Twilio is a cloud communication platform supporting 40,000+customers, 1+ Million Developers, handling millions of messages per minute across the globe from various different sectors. There are many regulated industries and parts of the world where data needs to be moved, stored and accessed securely. Twilio provides firm foundation for that and is focused towards providing customers a secure and scalable telecommunication cloud platform.
Handling this massive amount of data in secured way is possible because of Kafka and Spark. Twilio’s Data platform team is building a compliance layer on top of Data Pipeline, Data Lake and Bulk Data Transformer to handle different compliance requirements such as GDPR, HIPAA, PCI etc. Secured Data Pipeline is a streaming channel for Data Lake, BI Data Warehouse and Elastic Search whereas Bulk Data Transformer is a ETL channel to transfer and transform bulk data from RDMS. Kafka Connect, Spark SQL and Data frames powers streaming channel and makes data wrangling and de-duping efficient.
The Data Compliance layer has various components such as Data Anonymization, Authentication, Authorization, Auditing, Custom Retention and Data Deletion to handle the requirements of Processor and Controller. Anonymization as a service provides redaction, encryption and data obfuscation and is based on the varying needs of compliance and customers. Role based Access Control is applied on Kafka layers and S3 Layers to make sure only valid systems and users can access the critical data and rest of them will access to have only redacted data. Auditing service tracks all the access to various resources both from processor and controller perspective. Distributed Spark executor model makes the petabytes of data deletion efficient after the custom retention period. Thus scalable, fault-tolerant, distributed, secured, audited data governance pipeline is possible through Kafka, Kafka connect and Spark.

Spark and Online Analytics: Spark Summit East talky by Shubham Chopra
Apache Spark was designed as a batch analytics system. By caching RDDs, Spark speeds up jobs that iteratively process the same data. This pattern is also applicable to online analytics. We use Bloomberg’s Spark Server as a server runtime for online analytics. Our framework implements certain useful patterns applicable to online query processing and is centered on the idea of “Managed” DataFrames that can be refreshed and updated as per user requirements, without violating the immutability of RDDs/DataFrames. However, Spark presents significant challenges with respect to availability and resilience in an online setting where Spark is required to respond to queries with high SLAs. In this talk, we try to identify specific areas where slow-down or failures can result in the largest hits on online-query performance and potential solutions to address these.

A new serverless technology is also used in the architecture to support a dynamic and flexible implementations. The presenter will also outline how the platform was integrated with the Spark eco-system, including AI and ML tools, to simplify the development process
Real-Time Fraud Detection at Scale—Integrating Real-Time Deep-Link Graph Anal...
As data grows in size and connectedness dramatically in all dimensions, the potential for graph-enriched machine learning grows likewise, but scalable technologies are needed to both build models and apply them in real-time. Real-time deep-link graph pattern matching and analytics provides new opportunities for enriching your machine learning models with graph features.
‘In addition to the real-time deep-link aspect, the ability to process large datasets in a production pipeline provides a synergistic approach for the two distributed and performant platforms: Spark and TigerGraph. The TigerGraph graph database provides scalable real-time deep link graph analytics and augments Spark with graph analytics and predictions for a wide range of Machine Learning use cases.
In this session, we will explain the architecture and technical implementation for a TigerGraph+Spark graph-enhanced Machine Learning pipeline: Use TigerGraph both before training to extract (graph and non-graph) features and after training to apply the model on streaming data; use Spark to train and tune machine learning models at scale. As an example, we will present a solution in production at China Mobile that detects and prevents phone-based scams using machine learning with TigerGraph.
Specifically, the solution generates 118 graph features for 600 million users, to feed a machine learning system which detects three types of unwanted phone calls. TigerGraph then helps to deploy the model by extracting these 118 features in real-time for up to 10,000 calls per second, to give customers a real-time diagnosis of their incoming calls.
Virtualizing Analytics with Apache Spark: Keynote by Arsalan Tavakoli
In the race to invent multi-million dollar business opportunities with exclusive insights, data scientists and engineers are hampered by a multitude of challenges just to make one use case a reality – the need to ingest data from multiple sources, apply real-time analytics, build machine learning algorithms, and intermix different data processing models, all while navigating around their legacy data infrastructure that is just not up to the task. This need has created the demand for Virtual Analytics, where the complexities of disparate data and technology silos have been abstracted away, coupled with a powerful range of analytics and processing horsepower, all in one unified data platform. This talk describes how Databricks is powering this revolutionary new trend with Apache Spark.

Next we will show how we use Spark for analysis and clustering of malicious files and large scale experimentation to automatically process and handle changes in malware. In the end, we will give comparison to other tools we used for solving those problems.
An Update on Scaling Data Science Applications with SparkR in 2018 with Heiko...
Spark has established itself as the most popular platform for advanced scale-out analytical applications. It is deeply integrated with the Hadoop ecosystem, offers a set of powerful libraries and supports both Python and R. Because of these reasons Data Scientists have started to adopt Spark to train and deploy their models. When Spark 1.4 was released back in 2015, it included the new SparkR library: this API gave R users the exciting new option to run R code on Spark.
And while the initial promise to provide a full R environment in Spark has been kept, it takes a deeper understanding of SparkR’s inner workings to make optimal use of its capabilities. This talk will give a comprehensive update on where we stand with Data Science applications in R based on the latest Spark releases. We will share insights from both a Startup solution and a Fortune 100 company where SparkR does Machine Learning in the Cloud on a scale that would have not been feasible previously: it’s parallel execution model runs in minutes and hours whereas conventional sequential approaches would take days and months.
Suggested Topics:
• An update on the SparkR architecture in the latest Spark release: using R with SparkSQL, MLlib and Spark’s Structured Streaming
• How to handle practical challenges, e.g. running R on the cluster without a local installation, storing non-tabular results, such as Data Science models or plots, mixing Scala and R.
• Scaling Big Compute Applications with SparkR: Parallelizing SparkR applications with User-Defined Functions (UDFs) and elastic scaling of resources in the Cloud
• An Outlook on Machine Learning with SparkR and its ecosystem, frameworks and tools.
• Plus: “Do I need to learn Python?”

Deep Learning for Large-Scale Online Fraud Detection—Fighting Fraudsters Amon...
Here we present a real-time, scalable online fraud detection solution backed by deep learning technique. Nowadays, most deep learning applications are seen in actively studied fields including computer vision, natural language processing, etc. Our current solution represents one of the few production examples where deep learning models are applied to security problems. Our results demonstrate that deep learning solution outforms traditional blacklist and machine learning approaches significantly at terabyte-data scale.
Online fraud is largely orchestrated by organized crime rings. Coordinated malicious user accounts, either created anew, or obtained via user hijacking, actively target the various modern online service for real-world financial gain. Existing fraud solutions either rely on reputation lists for blocking known suspicious activities, or require extensive feature engineering by human analysts for model training. These approaches do not adapt well to changing fraud patterns nor are able to scale to large data volumes. At DataVisor, we analyze activities from billions of accounts across global online services to detect fraud and abuse. These data gives us unique insights into the online fraud landscape that allow us to tackle the coordinated fraud attacks holistically.
Our deep learning solution is based on digital information commonly collected by online services, including IP addresses, user-agent strings, email domains, user nicknames, etc. We build a general fraud detection framework which can identify fraudulent activities in log data that contain (all or a subnet of) these common digital information. By leveraging common digital information, the model is agnostic to the specific application or service from which data queries originate. We discuss the design and implementation of our deep learning pipeline based on Spark and Tensorflow that is built to fit our multi-cloud, real-time production requirements. We also demonstrate how our system outperforms traditional solutions including blacklists and machine learning methods.
Transforming AI with Graphs: Real World Examples using Spark and Neo4j

How to Rebuild an End-to-End ML Pipeline with Databricks and Upwork with Than...
Upwork has the biggest closed-loop online dataset of jobs and job seekers in labor history (>10M Profiles, >100M Job Posts, Job Proposals and Hiring Decisions, >10B of Messages, Transaction and Feedback Data). Besides sheer quantity, our data is also contextually very rich. We have client and contractor data for the entire job-funnel – from finding jobs to getting the job done.
For various machine learning applications including search and recommendations and labor marketplace optimization (rate, supply and demand), we heavily relied on a Greenplum-based data warehouse solution for data processing and ad-hoc ML pipelines (weka, scikit-learn, R) for offline model development and online model scoring.
In this talk, we present our modernization efforts in moving towards a 1) holistic data processing infrastructure for batch and stream data processing using S3, Kinesis, Spark and Spark Structured Streaming 2) model development using Spark MLlib and other ML libraries for Spark 3) model serving using Databricks Model Scoring, Scoring over Structured Streams and microservices and 3) how we orchestrate and streamline all these processes using Apache Airflow and a CI/CD workflow customized to our Data Science product engineering needs. The focus of this talk is on how we were able to leverage the Databricks service offering to reduce DevOps overhead and costs, complete the entire modernization with moderate efforts and adopt a collaborative notebook-based solution for all our data scientists to develop model, reuse features and share results. We will shared the core lessons learned and pitfalls we encountered during this journey.
Large-Scale Malicious Domain Detection with Spark AI
Malicious domains are one of the main resources used to mount attacks over the Internet. It is important to detect such activities by mining the large-scale network traffic data and identifying malicious URLs, domains or IPs. The attackers often take advantages of vulnerabilities in DNS and commit activities such as stealing private information, spamming, phishing, and DDoS attacks, and tend to by-pass botnet detection by generating domain clusters from Domain Generation Algorithms (DGA). We have billions of DNS records per day. Spark AI platform hence serves as an efficient distributed platform for the processing and mining of this huge amount of data. We work on the following two cybersecurity use cases. 1. Detect DGA, Porn, and Gambling domains Each malware-compromised host machine will have a large amount of DNS request in sequential order. The domain names are either generated by DGAs or preserve particular string patterns by design. We use spark to generate DNS request domain sequences and use Word2Vec to estimate the embedding of the domains. We then estimate the similarity and the most similar domains in the embedding space are discovered as the potential malicious domains. 2. Detect cryptocurrency mining pool domains The attackers are interested in accessing computing resources to mine cryptocurrency. The malware infected computers will be directed to attacker-controlled mining pool domains. This type of DNS request does not preserve sequential order and is relatively random. Since each mining pool domain cluster is visited by a wide range of different host machines, we used LSH to evaluate the similarity among sets of hosts. As a result, LSH generates domain-bucket bipartite graph and FastUnfolding algorithm is used to discover the domain clusters. We leveraged spark AI for large scale DNS data analysis and discovered hundreds of thousands of malicious domains each day at high precision.

With millions of visitors each month, we have petabytes of purchase, click-stream, product and other data in our data lake. This data is crucial to powering insights on shopper behavior and driving an AI-first strategy to improve site engagement.
Over 7 months ago, Zalando adopted Apache Spark, Delta Lake and Databricks as its de-facto computation platform for analytics and machine learning. During this period, we onboarded well over 50 internal teams ranging from BI teams, with no knowledge of Spark or big data running ETL pipelines to AI/ML teams already using EMR and Spark for heavy model training. Provided the spectrum of varied business problems they were trying to solve, we worked with each team individually, understanding their use cases, helping them validate assumptions, developing working code and taking them to production. In this talk we will share best practices for building a unified data and analytics architecture on Databricks, lessons learned rolling it out across the organization and provide a deep dive on AI & Analytics use cases in the fashion ecommerce space.
Apache Spark-Based Stratification Library for Machine Learning Use Cases at N...
Building flexible machine learning libraries adapted for Netflix’s use cases is paramount in our continued efforts to better model our users’ behaviors and provide them great personalized video recommendations.
This talk introduces one such spark-based stratification library developed at Netflix to aid “Training Set Stratification” in offline machine learning workflows. Originally created to implement user selection algorithms in our data snapshotting infrastructure, the library has evolved to cater to general-purpose stratification use cases in ML pipelines. We will talk about how using the stratification library’s DSL (domain specific language) and its underlying Spark based implementation, one can easily express complex sampling rules and dynamically carve out matching portions of a Spark dataframe.
For example, arbitrary rules governing the distributions of user attributes (and combinations there of) such as origin country, video play frequency, tenure etc can be easily enforced when constructing a ML training data set. The demo section of the talk will showcase example usages of the stratification library in a Jupyter notebook.
Building Sessionization Pipeline at Scale with Databricks Delta
"Comcast has made a concerted effort to transform itself from a cable/ISP company to a technology company. Data-driven decision making is at the heart of this transformation, and we use data to understand how customers interact with our products, and we see data as the most truthful representation of the voice of our customer. My team, Product Analytics & behavior science (PABS) team plays the role as interpreter, transforming data into consumable insights.
The X1 entertainment operating system, is one of the largest video streaming platforms in the world, and our customers consume more than a billion hours of content a week on X1. Our team consumes X1 telemetry at a rate of more than 25TBs of data per day and uses this data to inform our product teams members about the performance of and engagement with the platform. We also use this data to research customer behaviors to help better inform our product team members about areas of opportunity in our products, which range from fixing bugs to creating new features.
To power these insights, we need to have a reliable real-time data pipelines to deliver these insights, and we need our data scientists and data engineers to be able to quickly and efficiently be able to develop and commit new code to ensure we can measure new features the product teams are developing. To do this in an environment at this scale, we have been using Databricks, and Databricks delta to gain operational efficiencies, optimization and cost savings.
Some of the features from delta that we took advantage of to achieve the desired levels of efficiencies, optimization and cost savings are:
· Distributed writes to s3 (essentially eliminating 500 errors)
· s3 log with fast reads and ACID transactions (massive increases in s3 scans/reads, and enabling consistent views of the bucket/table)
· Vacuum
· Pptimize (which has allowed us to reduce a 640 node job to 40, and massively increase efficiencies of our clusters as well as our DS/DE’s)"

Spark and Online Analytics: Spark Summit East talky by Shubham Chopra
Apache Spark was designed as a batch analytics system. By caching RDDs, Spark speeds up jobs that iteratively process the same data. This pattern is also applicable to online analytics. We use Bloomberg’s Spark Server as a server runtime for online analytics. Our framework implements certain useful patterns applicable to online query processing and is centered on the idea of “Managed” DataFrames that can be refreshed and updated as per user requirements, without violating the immutability of RDDs/DataFrames. However, Spark presents significant challenges with respect to availability and resilience in an online setting where Spark is required to respond to queries with high SLAs. In this talk, we try to identify specific areas where slow-down or failures can result in the largest hits on online-query performance and potential solutions to address these.

Real-Time Fraud Detection at Scale—Integrating Real-Time Deep-Link Graph Anal...
As data grows in size and connectedness dramatically in all dimensions, the potential for graph-enriched machine learning grows likewise, but scalable technologies are needed to both build models and apply them in real-time. Real-time deep-link graph pattern matching and analytics provides new opportunities for enriching your machine learning models with graph features.
‘In addition to the real-time deep-link aspect, the ability to process large datasets in a production pipeline provides a synergistic approach for the two distributed and performant platforms: Spark and TigerGraph. The TigerGraph graph database provides scalable real-time deep link graph analytics and augments Spark with graph analytics and predictions for a wide range of Machine Learning use cases.
In this session, we will explain the architecture and technical implementation for a TigerGraph+Spark graph-enhanced Machine Learning pipeline: Use TigerGraph both before training to extract (graph and non-graph) features and after training to apply the model on streaming data; use Spark to train and tune machine learning models at scale. As an example, we will present a solution in production at China Mobile that detects and prevents phone-based scams using machine learning with TigerGraph.
Specifically, the solution generates 118 graph features for 600 million users, to feed a machine learning system which detects three types of unwanted phone calls. TigerGraph then helps to deploy the model by extracting these 118 features in real-time for up to 10,000 calls per second, to give customers a real-time diagnosis of their incoming calls.
Virtualizing Analytics with Apache Spark: Keynote by Arsalan Tavakoli
In the race to invent multi-million dollar business opportunities with exclusive insights, data scientists and engineers are hampered by a multitude of challenges just to make one use case a reality – the need to ingest data from multiple sources, apply real-time analytics, build machine learning algorithms, and intermix different data processing models, all while navigating around their legacy data infrastructure that is just not up to the task. This need has created the demand for Virtual Analytics, where the complexities of disparate data and technology silos have been abstracted away, coupled with a powerful range of analytics and processing horsepower, all in one unified data platform. This talk describes how Databricks is powering this revolutionary new trend with Apache Spark.

In the end, we will give comparison to other tools we used for solving those problems.
An Update on Scaling Data Science Applications with SparkR in 2018 with Heiko...
Spark has established itself as the most popular platform for advanced scale-out analytical applications. It is deeply integrated with the Hadoop ecosystem, offers a set of powerful libraries and supports both Python and R. Because of these reasons Data Scientists have started to adopt Spark to train and deploy their models. When Spark 1.4 was released back in 2015, it included the new SparkR library: this API gave R users the exciting new option to run R code on Spark.
And while the initial promise to provide a full R environment in Spark has been kept, it takes a deeper understanding of SparkR’s inner workings to make optimal use of its capabilities. This talk will give a comprehensive update on where we stand with Data Science applications in R based on the latest Spark releases. We will share insights from both a Startup solution and a Fortune 100 company where SparkR does Machine Learning in the Cloud on a scale that would have not been feasible previously: it’s parallel execution model runs in minutes and hours whereas conventional sequential approaches would take days and months.
Suggested Topics:
• An update on the SparkR architecture in the latest Spark release: using R with SparkSQL, MLlib and Spark’s Structured Streaming
• How to handle practical challenges, e.g. running R on the cluster without a local installation, storing non-tabular results, such as Data Science models or plots, mixing Scala and R.
• Scaling Big Compute Applications with SparkR: Parallelizing SparkR applications with User-Defined Functions (UDFs) and elastic scaling of resources in the Cloud
• An Outlook on Machine Learning with SparkR and its ecosystem, frameworks and tools.
• Plus: “Do I need to learn Python?”

Deep Learning for Large-Scale Online Fraud Detection—Fighting Fraudsters Amon...
Here we present a real-time, scalable online fraud detection solution backed by deep learning technique. Nowadays, most deep learning applications are seen in actively studied fields including computer vision, natural language processing, etc. Our current solution represents one of the few production examples where deep learning models are applied to security problems. Our results demonstrate that deep learning solution outforms traditional blacklist and machine learning approaches significantly at terabyte-data scale.
Online fraud is largely orchestrated by organized crime rings. Coordinated malicious user accounts, either created anew, or obtained via user hijacking, actively target the various modern online service for real-world financial gain. Existing fraud solutions either rely on reputation lists for blocking known suspicious activities, or require extensive feature engineering by human analysts for model training. These approaches do not adapt well to changing fraud patterns nor are able to scale to large data volumes. At DataVisor, we analyze activities from billions of accounts across global online services to detect fraud and abuse. These data gives us unique insights into the online fraud landscape that allow us to tackle the coordinated fraud attacks holistically.
Our deep learning solution is based on digital information commonly collected by online services, including IP addresses, user-agent strings, email domains, user nicknames, etc. We build a general fraud detection framework which can identify fraudulent activities in log data that contain (all or a subnet of) these common digital information. By leveraging common digital information, the model is agnostic to the specific application or service from which data queries originate. We discuss the design and implementation of our deep learning pipeline based on Spark and Tensorflow that is built to fit our multi-cloud, real-time production requirements. We also demonstrate how our system outperforms traditional solutions including blacklists and machine learning methods.

Upwork has the biggest closed-loop online dataset of jobs and job seekers in labor history (>10M Profiles, >100M Job Posts, Job Proposals and Hiring Decisions, >10B of Messages, Transaction and Feedback Data). Besides sheer quantity, our data is also contextually very rich. We have client and contractor data for the entire job-funnel – from finding jobs to getting the job done.
For various machine learning applications including search and recommendations and labor marketplace optimization (rate, supply and demand), we heavily relied on a Greenplum-based data warehouse solution for data processing and ad-hoc ML pipelines (weka, scikit-learn, R) for offline model development and online model scoring.
In this talk, we present our modernization efforts in moving towards a 1) holistic data processing infrastructure for batch and stream data processing using S3, Kinesis, Spark and Spark Structured Streaming 2) model development using Spark MLlib and other ML libraries for Spark 3) model serving using Databricks Model Scoring, Scoring over Structured Streams and microservices and 3) how we orchestrate and streamline all these processes using Apache Airflow and a CI/CD workflow customized to our Data Science product engineering needs. The focus of this talk is on how we were able to leverage the Databricks service offering to reduce DevOps overhead and costs, complete the entire modernization with moderate efforts and adopt a collaborative notebook-based solution for all our data scientists to develop model, reuse features and share results. We will shared the core lessons learned and pitfalls we encountered during this journey.
Large-Scale Malicious Domain Detection with Spark AI
Malicious domains are one of the main resources used to mount attacks over the Internet. It is important to detect such activities by mining the large-scale network traffic data and identifying malicious URLs, domains or IPs. The attackers often take advantages of vulnerabilities in DNS and commit activities such as stealing private information, spamming, phishing, and DDoS attacks, and tend to by-pass botnet detection by generating domain clusters from Domain Generation Algorithms (DGA). We have billions of DNS records per day. Spark AI platform hence serves as an efficient distributed platform for the processing and mining of this huge amount of data. We work on the following two cybersecurity use cases. 1. Detect DGA, Porn, and Gambling domains Each malware-compromised host machine will have a large amount of DNS request in sequential order. The domain names are either generated by DGAs or preserve particular string patterns by design. We use spark to generate DNS request domain sequences and use Word2Vec to estimate the embedding of the domains. We then estimate the similarity and the most similar domains in the embedding space are discovered as the potential malicious domains. 2. Detect cryptocurrency mining pool domains The attackers are interested in accessing computing resources to mine cryptocurrency. The malware infected computers will be directed to attacker-controlled mining pool domains. This type of DNS request does not preserve sequential order and is relatively random. Since each mining pool domain cluster is visited by a wide range of different host machines, we used LSH to evaluate the similarity among sets of hosts. As a result, LSH generates domain-bucket bipartite graph and FastUnfolding algorithm is used to discover the domain clusters. We leveraged spark AI for large scale DNS data analysis and discovered hundreds of thousands of malicious domains each day at high precision.

The state of the art in productionizing machine Learning models today primarily addresses building RESTful APIs. In the Digital Ecosystem, RESTful APIs are a necessary, but not sufficient, part of the complete solution for productionizing ML models. And according to recent research by the McKinsey Global Institute, applying AI in marketing and sales has the most potential value.
In the digital ecosystem, productionizing ML models at an accelerated pace becomes easy with:
Feature Store with commonly used features that is available for all data scientists
Feature Stores that distill visitor behavior is ready to use feature vectors in a semi supervised manner
Data pipeline that can support the challenging demands of the digital ecosystem to feed the Feature Store on an ongoing basis
Pipeline templates that support the challenging demands of the digital ecosystem that feed feature store, predict and distribute predictions on an ongoing basis. With these, a major electronics manufacturer was able to build and productionize a new model in 3 weeks.
The use case for the model is retargeting advertising; it analyzes the behavior of website visitors and builds customized audiences of the visitors that are most likely to purchase 9 different products. Using the model, this manufacturer was able to maintain the same level of purchases with half of the retargeting media spend -increasing the efficiency of their marketing spend by 100%.

Assessing New Databases– Translytical Use Cases
Organizations run their day-in-and-day-out businesses with transactional applications and databases. On the other hand, organizations glean insights and make critical decisions using analytical databases and business intelligence tools.
The transactional workloads are relegated to database engines designed and tuned for transactional high throughput. Meanwhile, the big data generated by all the transactions require analytics platforms to load, store, and analyze volumes of data at high speed, providing timely insights to businesses.
Thus, in conventional information architectures, this requires two different database architectures and platforms: online transactional processing (OLTP) platforms to handle transactional workloads and online analytical processing (OLAP) engines to perform analytics and reporting.
Today, a particular focus and interest of operational analytics includes streaming data ingest and analysis in real time. Some refer to operational analytics as hybrid transaction/analytical processing (HTAP), translytical, or hybrid operational analytic processing (HOAP). We’ll address if this model is a way to create efficiencies in our environments.

Many data scientists are well grounded in creating accomplishment in the enterprise, but many come from outside – from academia, from PhD programs and research. They have the necessary technical skills, but it doesn’t count until their product gets to production and in use. The speaker recently helped a struggling data scientist understand his organization and how to create success in it. That turned into this presentation, because many new data scientists struggle with the complexities of an enterprise.
Massive-Scale Entity Resolution Using the Power of Apache Spark and Graph
Spark's graph capabilities are great at enabling analysis of networks for use-cases such as fraud-detection, illicit network detection, and supply chain risk analysis. However, in order for a data scientist to perform analytics on a network (e.g., Page Rank, community detection, etc.), they end up spending all their time fighting a mountain of data integration challenges. A specific challenge this talk will focus on is connecting entities in a network within and across data domains. We will explore how you can leverage the Spark ecosystem's graph capabilities to perform massive-scale entity resolution (ER). As a result, your data scientists will be able to more quickly and effectively perform graph analytics that drive business and mission value.

5 Critical Steps to Clean Your Data Swamp When Migrating Off of Hadoop
In this session, learn how to quickly supplement your on-premises Hadoop environment with a simple, open, and collaborative cloud architecture that enables you to generate greater value with scaled application of analytics and AI on all your data. You will also learn five critical steps for a successful migration to the Databricks Lakehouse Platform along with the resources available to help you begin to re-skill your data teams.
Democratizing Data Quality Through a Centralized Platform
Bad data leads to bad decisions and broken customer experiences. Organizations depend on complete and accurate data to power their business, maintain efficiency, and uphold customer trust. With thousands of datasets and pipelines running, how do we ensure that all data meets quality standards, and that expectations are clear between producers and consumers? Investing in shared, flexible components and practices for monitoring data health is crucial for a complex data organization to rapidly and effectively scale.
At Zillow, we built a centralized platform to meet our data quality needs across stakeholders. The platform is accessible to engineers, scientists, and analysts, and seamlessly integrates with existing data pipelines and data discovery tools. In this presentation, we will provide an overview of our platform’s capabilities, including:
Giving producers and consumers the ability to define and view data quality expectations using a self-service onboarding portal
Performing data quality validations using libraries built to work with spark
Dynamically generating pipelines that can be abstracted away from users
Flagging data that doesn’t meet quality standards at the earliest stage and giving producers the opportunity to resolve issues before use by downstream consumers
Exposing data quality metrics alongside each dataset to provide producers and consumers with a comprehensive picture of health over time
Learn to Use Databricks for Data Science
Data scientists face numerous challenges throughout the data science workflow that hinder productivity. As organizations continue to become more data-driven, a collaborative environment is more critical than ever — one that provides easier access and visibility into the data, reports and dashboards built against the data, reproducibility, and insights uncovered within the data.. Join us to hear how Databricks’ open and collaborative platform simplifies data science by enabling you to run all types of analytics workloads, from data preparation to exploratory analysis and predictive analytics, at scale — all on one unified platform.
Why APM Is Not the Same As ML Monitoring
Application performance monitoring (APM) has become the cornerstone of software engineering allowing engineering teams to quickly identify and remedy production issues. However, as the world moves to intelligent software applications that are built using machine learning, traditional APM quickly becomes insufficient to identify and remedy production issues encountered in these modern software applications.
As a lead software engineer at NewRelic, my team built high-performance monitoring systems including Insights, Mobile, and SixthSense. As I transitioned to building ML Monitoring software, I found the architectural principles and design choices underlying APM to not be a good fit for this brand new world. In fact, blindly following APM designs led us down paths that would have been better left unexplored.
In this talk, I draw upon my (and my team’s) experience building an ML Monitoring system from the ground up and deploying it on customer workloads running large-scale ML training with Spark as well as real-time inference systems. I will highlight how the key principles and architectural choices of APM don’t apply to ML monitoring. You’ll learn why, understand what ML Monitoring can successfully borrow from APM, and hear what is required to build a scalable, robust ML Monitoring architecture.
The Function, the Context, and the Data—Enabling ML Ops at Stitch Fix
Autonomy and ownership are core to working at Stitch Fix, particularly on the Algorithms team. We enable data scientists to deploy and operate their models independently, with minimal need for handoffs or gatekeeping. By writing a simple function and calling out to an intuitive API, data scientists can harness a suite of platform-provided tooling meant to make ML operations easy. In this talk, we will dive into the abstractions the Data Platform team has built to enable this. We will go over the interface data scientists use to specify a model and what that hooks into, including online deployment, batch execution on Spark, and metrics tracking and visualization.
Stage Level Scheduling Improving Big Data and AI Integration
In this talk, I will dive into the stage level scheduling feature added to Apache Spark 3.1. Stage level scheduling extends upon Project Hydrogen by improving big data ETL and AI integration and also enables multiple other use cases. It is beneficial any time the user wants to change container resources between stages in a single Apache Spark application, whether those resources are CPU, Memory or GPUs. One of the most popular use cases is enabling end-to-end scalable Deep Learning and AI to efficiently use GPU resources. In this type of use case, users read from a distributed file system, do data manipulation and filtering to get the data into a format that the Deep Learning algorithm needs for training or inference and then sends the data into a Deep Learning algorithm. Using stage level scheduling combined with accelerator aware scheduling enables users to seamlessly go from ETL to Deep Learning running on the GPU by adjusting the container requirements for different stages in Spark within the same application. This makes writing these applications easier and can help with hardware utilization and costs.
There are other ETL use cases where users want to change CPU and memory resources between stages, for instance there is data skew or perhaps the data size is much larger in certain stages of the application. In this talk, I will go over the feature details, cluster requirements, the API and use cases. I will demo how the stage level scheduling API can be used by Horovod to seamlessly go from data preparation to training using the Tensorflow Keras API using GPUs.
The talk will also touch on other new Apache Spark 3.1 functionality, such as pluggable caching, which can be used to enable faster dataframe access when operating from GPUs.
Simplify Data Conversion from Spark to TensorFlow and PyTorch
In this talk, I would like to introduce an open-source tool built by our team that simplifies the data conversion from Apache Spark to deep learning frameworks.
Imagine you have a large dataset, say 20 GBs, and you want to use it to train a TensorFlow model. Before feeding the data to the model, you need to clean and preprocess your data using Spark. Now you have your dataset in a Spark DataFrame. When it comes to the training part, you may have the problem: How can I convert my Spark DataFrame to some format recognized by my TensorFlow model?
The existing data conversion process can be tedious. For example, to convert an Apache Spark DataFrame to a TensorFlow Dataset file format, you need to either save the Apache Spark DataFrame on a distributed filesystem in parquet format and load the converted data with third-party tools such as Petastorm, or save it directly in TFRecord files with spark-tensorflow-connector and load it back using TFRecordDataset. Both approaches take more than 20 lines of code to manage the intermediate data files, rely on different parsing syntax, and require extra attention for handling vector columns in the Spark DataFrames. In short, all these engineering frictions greatly reduced the data scientists’ productivity.
The Databricks Machine Learning team contributed a new Spark Dataset Converter API to Petastorm to simplify these tedious data conversion process steps. With the new API, it takes a few lines of code to convert a Spark DataFrame to a TensorFlow Dataset or a PyTorch DataLoader with default parameters.
In the talk, I will use an example to show how to use the Spark Dataset Converter to train a Tensorflow model and how simple it is to go from single-node training to distributed training on Databricks.
Scaling your Data Pipelines with Apache Spark on Kubernetes
There is no doubt Kubernetes has emerged as the next generation of cloud native infrastructure to support a wide variety of distributed workloads. Apache Spark has evolved to run both Machine Learning and large scale analytics workloads. There is growing interest in running Apache Spark natively on Kubernetes. By combining the flexibility of Kubernetes and scalable data processing with Apache Spark, you can run any data and machine pipelines on this infrastructure while effectively utilizing resources at disposal.
In this talk, Rajesh Thallam and Sougata Biswas will share how to effectively run your Apache Spark applications on Google Kubernetes Engine (GKE) and Google Cloud Dataproc, orchestrate the data and machine learning pipelines with managed Apache Airflow on GKE (Google Cloud Composer). Following topics will be covered: – Understanding key traits of Apache Spark on Kubernetes- Things to know when running Apache Spark on Kubernetes such as autoscaling- Demonstrate running analytics pipelines on Apache Spark orchestrated with Apache Airflow on Kubernetes cluster.
Scaling and Unifying SciKit Learn and Apache Spark Pipelines
Pipelines have become ubiquitous, as the need for stringing multiple functions to compose applications has gained adoption and popularity. Common pipeline abstractions such as “fit” and “transform” are even shared across divergent platforms such as Python Scikit-Learn and Apache Spark.
Scaling pipelines at the level of simple functions is desirable for many AI applications, however is not directly supported by Ray’s parallelism primitives. In this talk, Raghu will describe a pipeline abstraction that takes advantage of Ray’s compute model to efficiently scale arbitrarily complex pipeline workflows. He will demonstrate how this abstraction cleanly unifies pipeline workflows across multiple platforms such as Scikit-Learn and Spark, and achieves nearly optimal scale-out parallelism on pipelined computations.
Attendees will learn how pipelined workflows can be mapped to Ray’s compute model and how they can both unify and accelerate their pipelines with Ray.
Sawtooth Windows for Feature Aggregations
In this talk about zipline, we will introduce a new type of windowing construct called a sawtooth window. We will describe various properties about sawtooth windows that we utilize to achieve online-offline consistency, while still maintaining high-throughput, low-read latency and tunable write latency for serving machine learning features.We will also talk about a simple deployment strategy for correcting feature drift – due operations that are not “abelian groups”, that operate over change data.
Redis + Apache Spark = Swiss Army Knife Meets Kitchen Sink
We want to present multiple anti patterns utilizing Redis in unconventional ways to get the maximum out of Apache Spark.All examples presented are tried and tested in production at Scale at Adobe. The most common integration is spark-redis which interfaces with Redis as a Dataframe backing Store or as an upstream for Structured Streaming. We deviate from the common use cases to explore where Redis can plug gaps while scaling out high throughput applications in Spark.
Niche 1 : Long Running Spark Batch Job – Dispatch New Jobs by polling a Redis Queue
· Why?
o Custom queries on top a table; We load the data once and query N times
· Why not Structured Streaming
· Working Solution using Redis
Niche 2 : Distributed Counters
· Problems with Spark Accumulators
· Utilize Redis Hashes as distributed counters
· Precautions for retries and speculative execution
· Pipelining to improve performance
Re-imagine Data Monitoring with whylogs and Spark
In the era of microservices, decentralized ML architectures and complex data pipelines, data quality has become a bigger challenge than ever. When data is involved in complex business processes and decisions, bad data can, and will, affect the bottom line. As a result, ensuring data quality across the entire ML pipeline is both costly, and cumbersome while data monitoring is often fragmented and performed ad hoc. To address these challenges, we built whylogs, an open source standard for data logging. It is a lightweight data profiling library that enables end-to-end data profiling across the entire software stack. The library implements a language and platform agnostic approach to data quality and data monitoring. It can work with different modes of data operations, including streaming, batch and IoT data.
In this talk, we will provide an overview of the whylogs architecture, including its lightweight statistical data collection approach and various integrations. We will demonstrate how the whylogs integration with Apache Spark achieves large scale data profiling, and we will show how users can apply this integration into existing data and ML pipelines.
Raven: End-to-end Optimization of ML Prediction Queries
Machine learning (ML) models are typically part of prediction queries that consist of a data processing part (e.g., for joining, filtering, cleaning, featurization) and an ML part invoking one or more trained models. In this presentation, we identify significant and unexplored opportunities for optimization. To the best of our knowledge, this is the first effort to look at prediction queries holistically, optimizing across both the ML and SQL components.
We will present Raven, an end-to-end optimizer for prediction queries. Raven relies on a unified intermediate representation that captures both data processing and ML operators in a single graph structure.
This allows us to introduce optimization rules that
(i) reduce unnecessary computations by passing information between the data processing and ML operators
(ii) leverage operator transformations (e.g., turning a decision tree to a SQL expression or an equivalent neural network) to map operators to the right execution engine, and
(iii) integrate compiler techniques to take advantage of the most efficient hardware backend (e.g., CPU, GPU) for each operator.
We have implemented Raven as an extension to Spark’s Catalyst optimizer to enable the optimization of SparkSQL prediction queries. Our implementation also allows the optimization of prediction queries in SQL Server. As we will show, Raven is capable of improving prediction query performance on Apache Spark and SQL Server by up to 13.1x and 330x, respectively. For complex models, where GPU acceleration is beneficial, Raven provides up to 8x speedup compared to state-of-the-art systems. As part of the presentation, we will also give a demo showcasing Raven in action.
Processing Large Datasets for ADAS Applications using Apache Spark
Semantic segmentation is the classification of every pixel in an image/video. The segmentation partitions a digital image into multiple objects to simplify/change the representation of the image into something that is more meaningful and easier to analyze [1][2]. The technique has a wide variety of applications ranging from perception in autonomous driving scenarios to cancer cell segmentation for medical diagnosis.
Exponential growth in the datasets that require such segmentation is driven by improvements in the accuracy and quality of the sensors generating the data extending to 3D point cloud data. This growth is further compounded by exponential advances in cloud technologies enabling the storage and compute available for such applications. The need for semantically segmented datasets is a key requirement to improve the accuracy of inference engines that are built upon them.
Streamlining the accuracy and efficiency of these systems directly affects the value of the business outcome for organizations that are developing such functionalities as a part of their AI strategy.
This presentation details workflows for labeling, preprocessing, modeling, and evaluating performance/accuracy. Scientists and engineers leverage domain-specific features/tools that support the entire workflow from labeling the ground truth, handling data from a wide variety of sources/formats, developing models and finally deploying these models. Users can scale their deployments optimally on GPU-based cloud infrastructure to build accelerated training and inference pipelines while working with big datasets. These environments are optimized for engineers to develop such functionality with ease and then scale against large datasets with Spark-based clusters on the cloud.
Massive Data Processing in Adobe Using Delta Lake
At Adobe Experience Platform, we ingest TBs of data every day and manage PBs of data for our customers as part of the Unified Profile Offering. At the heart of this is a bunch of complex ingestion of a mix of normalized and denormalized data with various linkage scenarios power by a central Identity Linking Graph. This helps power various marketing scenarios that are activated in multiple platforms and channels like email, advertisements etc. We will go over how we built a cost effective and scalable data pipeline using Apache Spark and Delta Lake and share our experiences.

Levelwise PageRank with Loop-Based Dead End Handling Strategy : SHORT REPORT ...
Abstract — Levelwise PageRank is an alternative method of PageRank computation which decomposes the input graph into a directed acyclic block-graph of strongly connected components, and processes them in topological order, one level at a time. This enables calculation for ranks in a distributed fashion without per-iteration communication, unlike the standard method where all vertices are processed in each iteration. It however comes with a precondition of the absence of dead ends in the input graph. Here, the native non-distributed performance of Levelwise PageRank was compared against Monolithic PageRank on a CPU as well as a GPU. To ensure a fair comparison, Monolithic PageRank was also performed on a graph where vertices were split by components. Results indicate that Levelwise PageRank is about as fast as Monolithic PageRank on the CPU, but quite a bit slower on the GPU. Slowdown on the GPU is likely caused by a large submission of small workloads, and expected to be non-issue when the computation is performed on massive graphs.

Algorithmic optimizations for Dynamic Levelwise PageRank (from STICD) : SHORT...
Techniques to optimize the pagerank algorithm usually fall in two categories. One is to try reducing the work per iteration, and the other is to try reducing the number of iterations. These goals are often at odds with one another. Skipping computation on vertices which have already converged has the potential to save iteration time. Skipping in-identical vertices, with the same in-links, helps reduce duplicate computations and thus could help reduce iteration time. Road networks often have chains which can be short-circuited before pagerank computation to improve performance. Final ranks of chain nodes can be easily calculated. This could reduce both the iteration time, and the number of iterations. If a graph has no dangling nodes, pagerank of each strongly connected component can be computed in topological order. This could help reduce the iteration time, no. of iterations, and also enable multi-iteration concurrency in pagerank computation. The combination of all of the above methods is the STICD algorithm. [sticd] For dynamic graphs, unchanged components whose ranks are unaffected can be skipped altogether.

Enhanced Enterprise Intelligence with your personal AI Data Copilot.pdf
Recently we have observed the rise of open-source Large Language Models (LLMs) that are community-driven or developed by the AI market leaders, such as Meta (Llama3), Databricks (DBRX) and Snowflake (Arctic). On the other hand, there is a growth in interest in specialized, carefully fine-tuned yet relatively small models that can efficiently assist programmers in day-to-day tasks. Finally, Retrieval-Augmented Generation (RAG) architectures have gained a lot of traction as the preferred approach for LLMs context and prompt augmentation for building conversational SQL data copilots, code copilots and chatbots.
In this presentation, we will show how we built upon these three concepts a robust Data Copilot that can help to democratize access to company data assets and boost performance of everyone working with data platforms.
Why do we need yet another (open-source ) Copilot?
How can we build one?

The Building Blocks of QuestDB, a Time Series Database
Talk Delivered at Valencia Codes Meetup 2024-06.
Traditionally, databases have treated timestamps just as another data type. However, when performing real-time analytics, timestamps should be first class citizens and we need rich time semantics to get the most out of our data. We also need to deal with ever growing datasets while keeping performant, which is as fun as it sounds.
It is no wonder time-series databases are now more popular than ever before. Join me in this session to learn about the internal architecture and building blocks of QuestDB, an open source time-series database designed for speed. We will also review a history of some of the changes we have gone over the past two years to deal with late and unordered data, non-blocking writes, read-replicas, or faster batch ingestion.
