1 like•485 views
Designing a streaming application which has to process data from 1 or 2 streams is easy. Any streaming framework which provides scalability, high-throughput, and fault-tolerance would work. But when the number of streams start growing in order 100s or 1000s, managing them can be daunting. How would you share resources among 1000s of streams with all of them running 24×7? Manage their state, Apply advanced streaming operations, Add/Delete streams without restarting? This talk explains common scenarios & shows techniques that can handle thousands of streams using Spark Structured Streaming.

Performance Analysis of Apache Spark and Presto in Cloud Environments
Today, users have multiple options for big data analytics in terms of open-source and proprietary systems as well as in cloud computing service providers. In order to obtain the best value for their money in a SaaS cloud environment, users need to be aware of the performance of each service as well as its associated costs, while also taking into account aspects such as usability in conjunction with monitoring, interoperability, and administration capabilities.
We present an independent analysis of two mature and well-known data analytics systems, Apache Spark and Presto. Both running on the Amazon EMR platform, but in the case of Apache Spark, we also analyze the Databricks Unified Analytics Platform and its associated runtime and optimization capabilities. Our analysis is based on running the TPC-DS benchmark and thus focuses on SQL performance, which still is indispensable for data scientists and engineers. In our talk we will present quantitative results that we expect to be valuable for end users, accompanied by an in depth look into the advantages and disadvantages of each alternative.
Thus, attendees will be better informed of the current big data analytics landscape and find themselves in a better position to avoid common pitfalls in deploying data analytics at a scale.

Application and Challenges of Streaming Analytics and Machine Learning on Multi-Variate Time Series Data for Smart Manufacturing
Auto-Pilot for Apache Spark Using Machine Learning
At Qubole, users run Spark at scale on cloud (900+ concurrent nodes). At such scale, for efficiently running SLA critical jobs, tuning Spark configurations is essential. But it continues to be a difficult undertaking, largely driven by trial and error. In this talk, we will address the problem of auto-tuning SQL workloads on Spark. The same technique can also be adapted for non-SQL Spark workloads. In our earlier work[1], we proposed a model based on simple rules and insights. It was simple yet effective at optimizing queries and finding the right instance types to run queries. However, with respect to auto tuning Spark configurations we saw scope of improvement. On exploration, we found previous works addressing auto-tuning using Machine learning techniques. One major drawback of the simple model[1] is that it cannot use multiple runs of query for improving recommendation, whereas the major drawback with Machine Learning techniques is that it lacks domain specific knowledge. Hence, we decided to combine both techniques. Our auto-tuner interacts with both models to arrive at good configurations. Once user selects a query to auto tune, the next configuration is computed from models and the query is run with it. Metrics from event log of the run is fed back to models to obtain next configuration. Auto-tuner will continue exploring good configurations until it meets the fixed budget specified by the user. We found that in practice, this method gives much better configurations compared to configurations chosen even by experts on real workload and converges soon to optimal configuration. In this talk, we will present a novel ML model technique and the way it was combined with our earlier approach. Results on real workload will be presented along with limitations and challenges in productionizing them. [1] Margoor et al,'Automatic Tuning of SQL-on-Hadoop Engines' 2018,IEEE CLOUD
How To Use Kafka and Druid to Tame Your Router Data (Rachel Pedreschi, Imply ...
Do you know who is knocking on your network’s door? Have new regulations left you scratching your head on how to handle what is happening in your network? Network flow data helps answer many questions across a multitude of use cases including network security, performance, capacity planning, routing, operational troubleshooting and more. Today’s modern day streaming data pipelines need to include tools that can scale to meet the demands of these service providers while continuing to provide responsive answers to difficult questions. In addition to stream processing, data needs to be stored in a redundant, operationally focused database to provide fast, reliable answers to critical questions. Together, Kafka and Druid work together to create such a pipeline.
In this talk Eric Graham and Rachel Pedreschi will discuss these pipelines and cover the following topics:
-Network flow use cases and why this data is important.
-Reference architectures from production systems at a major international Bank.
-Why Kafka and Druid and other OSS tools for Network Flows.
-A demo of one such system.
Scalable Monitoring Using Prometheus with Apache Spark Clusters with Diane F...
As Apache Spark applications move to a containerized environment, there are many questions about how to best configure server systems in the container world. In this talk we will demonstrate a set of tools to better monitor performance and identify optimal configuration settings. We will demonstrate how Prometheus, a project that is now part of the Cloud Native Computing Foundation (CNCF: https://www.cncf.io/projects/), can be applied to monitor and archive system performance data in a containerized spark environment.
In our examples, we will gather spark metric output through Prometheus and present the data with Grafana dashboards. We will use our examples to demonstrate how performance can be enhanced through different tuned configuration settings. Our demo will show how to configure settings across the cluster as well as within each node.
Distributed Models Over Distributed Data with MLflow, Pyspark, and Pandas
Does more data always improve ML models? Is it better to use distributed ML instead of single node ML?
In this talk I will show that while more data often improves DL models in high variance problem spaces (with semi or unstructured data) such as NLP, image, video more data does not significantly improve high bias problem spaces where traditional ML is more appropriate. Additionally, even in the deep learning domain, single node models can still outperform distributed models via transfer learning.
Data scientists have pain points running many models in parallel automating the experimental set up. Getting others (especially analysts) within an organization to use their models Databricks solves these problems using pandas udfs, ml runtime and MLflow.
AI-Powered Streaming Analytics for Real-Time Customer Experience
Interacting with customers in the moment and in a relevant, meaningful way can be challenging to organizations faced with hundreds of various data sources at the edge, on-premises, and in multiple clouds.
To capitalize on real-time customer data, you need a data management infrastructure that allows you to do three things:
1) Sense-Capture event data and stream data from a source, e.g. social media, web logs, machine logs, IoT sensors.
2) Reason-Automatically combine and process this data with existing data for context.
3) Act-Respond appropriately in a reliable, timely, consistent way. In this session we’ll describe and demo an AI powered streaming solution that can tackle the entire end-to-end sense-reason-act process at any latency (real-time, streaming, and batch) using Spark Structured Streaming.
The solution uses AI (e.g. A* and NLP for data structure inference and machine learning algorithms for ETL transform recommendations) and metadata to automate data management processes (e.g. parse, ingest, integrate, and cleanse dynamic and complex structured and unstructured data) and guide user behavior for real-time streaming analytics. It’s built on Spark Structured Streaming to take advantage of unified API’s, multi-latency and event time-based processing, out-of-order data delivery, and other capabilities.
You will gain a clear understanding of how to use Spark Structured Streaming for data engineering using an intelligent data streaming solution that unifies fast-lane data streaming and batch lane data processing to deliver in-the-moment next best actions that improve customer experience.
BigDL: A Distributed Deep Learning Library on Spark: Spark Summit East talk b...
BigDL is a distributed deep Learning framework built for Big Data platform using Apache Spark. It combines the benefits of “high performance computing” and “Big Data” architecture, providing native support for deep learning functionalities in Spark, orders of magnitude speedup than out-of-box open source DL frameworks (e.g., Caffe/Torch) wrt single node performance (by leveraging Intel MKL), and the scale-out of deep learning workloads based on the Spark architecture. We’ll also share how our users adopt BigDL for their deep learning applications (such as image recognition, object detection, NLP, etc.), which allows them to use their Big Data (e.g., Apache Hadoop and Spark) platform as the unified data analytics platform for data storage, data processing and mining, feature engineering, traditional (non-deep) machine learning, and deep learning workloads.

Going Real-Time: Creating Frequently-Updating Datasets for Personalization: S...
Streaming applications have often been complex to design and maintain because of the significant upfront infrastructure investment required. However, with the advent of Spark an easy transition to stream processing is now available, enabling personalization applications and experiments to consume near real-time data without massive development cycles.
Our decision to evaluate Spark as our stream processing engine was primarily led by the following considerations: 1) Ease of development for the team (already familiar with spark for batch), 2) the scope/requirements of our problem, 3) re-usability of code from spark batch jobs, and 4) Spark support from infrastructure teams within the company.
In this session, we will present our experience using Spark for stream processing unbounded datasets in the personalization space. The datasets consisted of, but were not limited, to the stream of playback events that are used as feedback for all personalization algorithms. These plays are used to extract specific behaviors which are highly predictive of a customer’s enjoyment of our service. This dataset is massive and has to be further enriched by other online and offline Netflix data sources. These datasets, when consumed by our machine learning models, directly affect the customer’s personalized experience, which means that the impact is high and tolerance for failure is low. We’ll talk about the experiments we did to compare Spark with other streaming solutions like Apache Flink , the impact that we had on our customers, and most importantly, the challenges we faced.
Take-aways for the audience:
1) A great example of stream processing large, personalization datasets at scale.
2) An increased awareness of the costs/requirements for making the transition from batch to streaming successfully.
3) Exposure to some of the technical challenges that should be expected along the way.
Simplify and Scale Data Engineering Pipelines with Delta Lake
We’re always told to ‘Go for the Gold!,’ but how do we get there? This talk will walk you through the process of moving your data to the finish fine to get that gold metal! A common data engineering pipeline architecture uses tables that correspond to different quality levels, progressively adding structure to the data: data ingestion (‘Bronze’ tables), transformation/feature engineering (‘Silver’ tables), and machine learning training or prediction (‘Gold’ tables). Combined, we refer to these tables as a ‘multi-hop’ architecture. It allows data engineers to build a pipeline that begins with raw data as a ‘single source of truth’ from which everything flows. In this session, we will show how to build a scalable data engineering data pipeline using Delta Lake, so you can be the champion in your organization.
Streaming Analytics for Financial Enterprises
Streaming Analytics (or Fast Data processing) is becoming an increasingly popular subject in the financial sector. There are two main reasons for this development. First, more and more data has to be analyze in real-time to prevent fraud; all transactions that are being processed by banks have to pass and ever-growing number of tests to make sure that the money is coming from and going to legitimate sources. Second, customers want to have friction-less mobile experiences while managing their money, such as immediate notifications and personal advise based on their online behavior and other users’ actions.
A typical streaming analytics solution follows a ‘pipes and filters’ pattern that consists of three main steps: detecting patterns on raw event data (Complex Event Processing), evaluating the outcomes with the aid of business rules and machine learning algorithms, and deciding on the next action. At the core of this architecture is the execution of predictive models that operate on enormous amounts of never-ending data streams.
In this talk, I’ll present an architecture for streaming analytics solutions that covers many use cases that follow this pattern: actionable insights, fraud detection, log parsing, traffic analysis, factory data, the IoT, and others. I’ll go through a few architecture challenges that will arise when dealing with streaming data, such as latency issues, event time vs server time, and exactly-once processing. The solution is build on the KISSS stack: Kafka, Ignite, and Spark Structured Streaming. The solution is open source and available on GitHub.
High Resolution Energy Modeling that Scales with Apache Spark 2.0 Spark Summi...
As advanced sensor technologies are becoming widely deployed in the energy industry, the availability of higher-frequency data results in both analytical benefits and computational costs. To an energy forecaster or data scientist, some of these benefits might include enhanced predictive performance from forecasting models as well as improved pattern recognition in energy consumption across building types, economic sectors, and geographies. To a utility or electricity service provider, these benefits might include significantly deeper insights into their diverse customer base. However, these advantages can come with a high computational price tag. With Spark 2.0, User-Defined Functions can be applied across grouped SparkDataFrames in the SparkR API to solve the multivariate optimization and model selection problems typically required for fitting site-level models. This recently added feature of Spark 2.0 on Databricks has allowed DNV GL to efficiently fit predictive models that relate weather, electricity, water, and gas consumption across virtually any number of buildings.

Pandas UDF: Scalable Analysis with Python and PySpark
Over the past few years, Python has become the default language for data scientists. Packages such as pandas, numpy, statsmodel, and scikit-learn have gained great adoption and become the mainstream toolkits. At the same time, Apache Spark has become the de facto standard in processing big data. Spark ships with a Python interface, aka PySpark, however, because Spark’s runtime is implemented on top of JVM, using PySpark with native Python library sometimes results in poor performance and usability.
In this talk, we introduce a new type of PySpark UDF designed to solve this problem – Vectorized UDF. Vectorized UDF is built on top of Apache Arrow and bring you the best of both worlds – the ability to define easy to use, high performance UDFs and scale up your analysis with Spark.
Petabytes, Exabytes, and Beyond: Managing Delta Lakes for Interactive Queries...
Data production continues to scale up and the techniques for managing it need to scale too. Building pipelines that can process petabytes per day in turn create data lakes with exabytes of historical data. At Databricks, we help our customers turn these data lakes into gold mines of valuable information using Apache Spark. This talk will cover techniques to optimize access to these data lakes using Delta Lakes, including range partitioning, file-based data skipping, multi-dimensional clustering, and read-optimized files. We'll cover sample implementations and see examples of querying petabytes of data in seconds, not hours. We'll also discuss tradeoffs that data engineers deal with everyday like read speed vs. write throughput, managing storage costs, and duplicating data to support multiple query profiles. We'll also discuss combining batch with streaming to achieve desired query performance. After this session, you will have new ideas for managing truly massive Delta Lakes.

GPU-Accelerating UDFs in PySpark with Numba and PyGDF
With advances in computer hardware such as 10 gigabit network cards, infiniband, and solid state drives all becoming commodity offerings, the new bottleneck in big data technologies is very commonly the processing power of the CPU. In order to meet the computational demand desired by users, enterprises have had to resort to extreme scale out approaches just to get the processing power they need. One of the most well known technologies in this space, Apache Spark, has numerous enterprises publicly talking about the challenges in running multiple 1000+ node clusters to give their users the processing power they need. This talk is based on work completed by NVIDIA’s Applied Solutions Engineering team. Attendees will learn how they were able to GPU-accelerate UDFs in PySpark using open source technologies such as Numba and PyGDF, the lessons they learned in the process, and how they were able to accelerate workloads in a fraction of the hardware footprint.

Packages such as pandas, numpy, statsmodel, and scikit-learn have gained great adoption and become the mainstream toolkits. At the same time, Apache Spark has become the de facto standard in processing big data. Spark ships with a Python interface, aka PySpark, however, because Spark’s runtime is implemented on top of JVM, using PySpark with native Python library sometimes results in poor performance and usability.
In this talk, we introduce a new type of PySpark UDF designed to solve this problem – Vectorized UDF. Vectorized UDF is built on top of Apache Arrow and bring you the best of both worlds – the ability to define easy to use, high performance UDFs and scale up your analysis with Spark.
Petabytes, Exabytes, and Beyond: Managing Delta Lakes for Interactive Queries...
Data production continues to scale up and the techniques for managing it need to scale too. Building pipelines that can process petabytes per day in turn create data lakes with exabytes of historical data. At Databricks, we help our customers turn these data lakes into gold mines of valuable information using Apache Spark. This talk will cover techniques to optimize access to these data lakes using Delta Lakes, including range partitioning, file-based data skipping, multi-dimensional clustering, and read-optimized files. We'll cover sample implementations and see examples of querying petabytes of data in seconds, not hours. We'll also discuss tradeoffs that data engineers deal with everyday like read speed vs. write throughput, managing storage costs, and duplicating data to support multiple query profiles. We'll also discuss combining batch with streaming to achieve desired query performance. After this session, you will have new ideas for managing truly massive Delta Lakes.

Democratizing Machine Learning: Perspective from a scikit-learn Creator
<p>Once an obscure branch of applied mathematics, machine learning is now the darling of tech. I will talk about lessons learned democratizing machine learning. How libraries like scikit-learn were designed to empower users: simplifying but avoiding ambiguous behaviors. How the Python data ecosystem was built from scientific computing tools: the importance of good numerics. How some machine-learning patterns easily provide value to real-world situations. I will also discuss remain challenges to address and the progresses that we are making. Scaling up brings different bottlenecks to numerics. Integrating data in the statistical models, a hurdle to data-science practice requires to rethink data cleaning pipelines.</p><p>This talk will drawn from my experience as a scikit-learn developer, but also as a researcher in machine learning and applications.</p>

GPU-Accelerating UDFs in PySpark with Numba and PyGDF
With advances in computer hardware such as 10 gigabit network cards, infiniband, and solid state drives all becoming commodity offerings, the new bottleneck in big data technologies is very commonly the processing power of the CPU. In order to meet the computational demand desired by users, enterprises have had to resort to extreme scale out approaches just to get the processing power they need. One of the most well known technologies in this space, Apache Spark, has numerous enterprises publicly talking about the challenges in running multiple 1000+ node clusters to give their users the processing power they need. This talk is based on work completed by NVIDIA’s Applied Solutions Engineering team. Attendees will learn how they were able to GPU-accelerate UDFs in PySpark using open source technologies such as Numba and PyGDF, the lessons they learned in the process, and how they were able to accelerate workloads in a fraction of the hardware footprint.

Designing a streaming application which has to process data from 1 or 2 streams is easy. Any streaming framework which provides scalability, high-throughput, and fault-tolerance would work. But when the number of streams starts growing in order 100s or 1000s, managing them can be daunting. How would you share resources among 1000s of streams with all of them running 24x7? Manage their state, Apply advanced streaming operations, Add/Delete streams without restarting? This talk explains common scenarios & shows techniques that can handle thousands of streams using Spark Structured Streaming.

Working with 1 Million Time Series a Day: How to Scale Up a Predictive Analyt...
Most predictive analytics projects no longer rely on the use of a single machine learning model. Instead, they leverage on a collection of different algorithms to be periodically evaluated against new data. This is because the currently best performing algorithm might no longer be the preferable one in the future. To deal with such ever-evolving frameworks, we can create architectures that include a few different algorithms which are run and confronted automatically every time a decision must be taken. We present a platform built with Apache Spark that predicts the evolution of the prices of about 150 thousand goods tracked in real time. The requirement was to analyze these time series data and predict the expected price, for each of the objects, in the five subsequent days. Our platform leverages Spark in two significant ways: 1. computational effort, in that every model and related parameters tweaks needs to be run on every object. For each of these objects our infrastructure identifies the optimal algorithm, and the related prediction is published. The process repeats every day. 2. storage capabilities, which are pivotal if we want to scale up to handle ever-growing data streams. Compared to the original single-machine code, switching to parallel computing allowed us to run and confront the models faster, which also opened up the possibilities to further experiment with different parameters and additional exogenous variables. Questions you'll be able to confidently answer after the session: - When does it make sense to set up a model based on a pool of different algorithms? - When is it time to switch to parallel computing? - What should I do if I want to scale up my model? - How complicated is it to turn an already-written, sequential model, to its parallel computing version?
Deploying Enterprise Scale Deep Learning in Actuarial Modeling at Nationwide
The traditional approach to insurance pricing involves fitting a generalized linear model (GLM) to data collected on historical claims payments and premiums received. The explosive growth in data availability and increasing competitiveness in the marketplace are challenging actuaries to find new insights in their data and make predictions with more granularity, improved speed and efficiency, and with tighter integration among business units to support strategic decisions.
In this session we will share our experience implementing deep hierarchical neural networks using TensorFlow and PySpark on Databricks. We will discuss the benefits of the ML Runtime, our experience using the goofys mount, our process for hyperparameter tuning, specific considerations for the large dataset size and extreme volatility present in insurance data, among other topics.

Operationalizing analytics to scale
Many companies have invested time and money into building sophisticated data pipelines that can move massive amounts of data, often in real time. However, for the analyst or data scientist who builds offline models, integrating their analyses into these pipelines for operational purposes can pose a challenge.
In this slide deck, we will discuss some key technologies and workflows companies can leverage to build end-to-end solutions for automating statistical and machine learning solutions: from collection and storage to analysis and real-time predictions.
Apache Spark Data Validation
In our experience, many problems with production workflows can be traced back to unexpected values in the input data. In a complex pipeline, it can be difficult and costly to trace the root cause of errors. Here we outline our work developing an open source data validation framework built on Apache Spark. Our goal is a tool that easily integrates into existing workflows to automatically make data validation a vital initial step of every production workflow. Our tool is aimed at data scientists and data engineers, who are not necessarily Scala/Python programmers. Our users specify a configuration file that details the data validation checks to be completed. This configuration file is parsed into appropriate queries that are executed with Apache Spark. A status report is logged, which is used to notify developers/maintainers and to establish a historical record of validator checks. This work was inspired by the many great ideas behind Google's TensorFlow Extended (TFX) platform, in particular TensorFlow Data Validation (TFDV). As such we provide optional functionality for our users to visualize their data using Facets Overview and Facets Dive.

Big Data in Business. Introduction to BigData.
"The Hunt For Alpha Among Alternative Data Sources" by Dr. Michael Halls-Moor...
Presented at QuantCon Singapore 2016, Quantopian's quantitative finance and algorithmic trading conference, November 11th.
The lifeblood of many quantitative trading strategies is a mix of high-quality, high-frequency asset pricing data and detailed information on company fundamentals. Such data is now available quite readily at low cost from multiple vendors. In addition it is more straightforward than ever to "wrangle" the data into the necessary formats for rapid quant research.
Quantitative hedge funds, family offices, proprietary trading houses and even some retail quants are realising that many of the traditional sources of alpha are decaying. In essence, the search for alpha must be continued elsewhere.
So-called "alternative" data sources are a relatively recent solution to the problem of alpha decay. Satellite imagery, email receipts, social media, Internet-of-Things sensors, weather patterns and earnings calls can all provide insights that lead to novel trading ideas.
Along with these new sources of data are methods to quantify and analyse it, including statistical machine learning, computer vision, sentiment analysis and deep neural networks.
In this talk we will consider these new data sets and discuss how we can apply freely-available data science tools to help find new alpha among them.
Simply Business' Data Platform
Simply Business is a leading insurance provider for small business in the UK and we are now growing to the USA. In this presentation, I explain how our data platform is evolving to keep delivering value and adapting to a company that changes really fast.
Stream Processing: Choosing the Right Tool for the Job
Due to the increasing interest in real-time processing, many stream processing frameworks were developed. However, no clear guidelines have been established for choosing a framework for a specific use case. In this talk, two different scenarios are taken and the audience is guided through the thought process and questions that one should ask oneself when choosing the right tool. The stream processing frameworks that will be discussed are Spark Streaming, Structured Streaming, Flink and Kafka Streams.
The main questions are:
How much data does it need to process? (throughput)
Does it need to be fast? (latency)
Who will build it? (supported languages, level of API, SQL capabilities, built-in windowing and joining functionalities, etc)
Is accurate ordering important? (event time vs. processing time)
Is there a batch component? (integration of batch API)
How do we want it to run? (deployment options: standalone, YARN, mesos, …)
How much state do we have? (state store options) – What if a message gets lost? (message delivery guarantees, checkpointing).
For each of these questions, we look at how each framework tackles this and what the main differences are. The content is based on the PhD research of Giselle van Dongen in benchmarking stream processing frameworks in several scenarios using latency, throughput and resource utilization.

At Sams Club we have a long history of using Apache Spark and Hadoop. Projects from all parts of the company use Apache Spark, from fraud detection to product recommendations. Because of the scale of our business with billions of transactions and trillions of events it is often essential to use big data technologies. Until recently all of this work has run on several large on-premise Hadoop clusters. As part of our transition to public cloud we needed to build out an enterprise scale data platform. Azure Databricks is a key component of this platform giving our data scientist, engineers, and business users the ability to easily work with the companies data. We will discuss our architecture considerations that lead to using multiple Databricks workspaces and external Azure blob storage. We will also discuss how we move massive amounts of data to Azure on a daily basis with Airflow. Further we will discuss the self-service tools that we created to help users get their data to Azure and for us to manage the platform. Finally we will discuss our security considerations and how that played out in our architecture.

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.

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.

Blue Pill/Red Pill: The Matrix of Thousands of Data Streams
- 1. WIFI SSID:Spark+AISummit | Password: UnifiedDataAnalytics
- 2. Knoldus Inc. Blue Pill / Red Pill : The Matrix of thousands of data streams #UnifiedDataAnalytics #SparkAISummit
- 3. ● My name is Himanshu Gupta ● Lead Consultant at Knoldus Inc. ● Twitter: @himanshug735 ● LinkedIn: https://www.linkedin.com/in/himanshu-gupta-25189629/ 3#UnifiedDataAnalytics #SparkAISummit About Me
- 4. ● The Need ● Challenges ● Our Solution ● Future Work 4#UnifiedDataAnalytics #SparkAISummit Agenda
- 5. 5#UnifiedDataAnalytics #SparkAISummit The Need: Make Better Use of Real-Time Data
- 6. 6#UnifiedDataAnalytics #SparkAISummit The Need: Make Better Use of Real-Time Data
- 7. 7#UnifiedDataAnalytics #SparkAISummit Benefits of Real-Time Data ● In 2014, real-time data analysis reduced crude mortality rate from 7.75% to 6.42% in Queen Alexandra Hospital in Portsmouth and University Hospital Coventry. ● World's largest Hedge Fund, Bridgewater, uses Twitter For Real-Time Economic Modeling.
- 8. 8#UnifiedDataAnalytics #SparkAISummit Solution: One Platform An End-to-end real-time data platform which can analyze and prepare data in a single platform-as-a- service.
- 9. 9#UnifiedDataAnalytics #SparkAISummit Challenge ● Collecting data from 1000s of streams is difficult. ● Using each stream for different purpose makes processing harder. ● Managing data of mission critical value is a challenge.
- 10. 10#UnifiedDataAnalytics #SparkAISummit How to overcome the challenges?
- 11. 11#UnifiedDataAnalytics #SparkAISummit Stream Data ● Streaming data into 1000s of streams is a resource intensive process. ● Since streaming requires dedicated resources, the number of streams supported by a system gets limited by the resources available. ● However, if combined, streams can be managed much more efficiently. ● Also, starting/stopping a stream becomes easy since data is managed by group.
- 12. 12#UnifiedDataAnalytics #SparkAISummit Group Data For example, consider a Power plant which has 100s of devices emitting data in real-time. The data contains information about different parameters of device like temperature, speed, etc. Since the data is coming from one source (power plant) it becomes a good candidate for grouping data into one stream.
- 13. 13#UnifiedDataAnalytics #SparkAISummit Output As Kafka is being used, the result of combining data from different streams into one looks like above. Where one key represents one device of the power plant from previous example.
- 14. 14#UnifiedDataAnalytics #SparkAISummit Analyze Data ● Analyzing combined/grouped data have many challenges. ● For example, applying different analytics on different data source. ● Or, managing state of each data source.
- 15. 15#UnifiedDataAnalytics #SparkAISummit Use Spark Since the introduction of Structured Streaming in Apache Spark 2.0, the way processing streams has changed a lot. As it has brought a lot of features which were earlier unheard.
- 16. 16#UnifiedDataAnalytics #SparkAISummit Why Spark? ● Provides support for ad-hoc queries, i.e., helps in applying different analytics on different data source. ● Manages state of each data source which via Arbitrary Stateful Operations.
- 17. 17#UnifiedDataAnalytics #SparkAISummit Store Data ● Storing data might look an easy task but it is not. ● Because after analysis of multiple data sources is done it is difficult to materialize it and save it in different locations. ● And, also saving in such a way that retrieving data becomes Easy.
- 18. 18#UnifiedDataAnalytics #SparkAISummit Again! Use Spark Apache Spark comes to rescue here as well. Spark Structured Streaming has support for 6 different types of output sinks.
- 19. 19#UnifiedDataAnalytics #SparkAISummit Result The data is saved in a hierarchical file system manner in AWS S3. Each sub file represents a device/data source in the power plant example.
