http://flink-forward.org/kb_sessions/flink-and-beam-current-state-roadmap/ It is no secret that the Dataflow model, which evolved from Google’s MapReduce, Flume, and MillWheel, has been a major influence to Apache Flink’s streaming API. The essentials of this model are captured in Apache Beam. Beam provides the Dataflow API with the option to deploy to various backends (e.g. Flink, Spark). In this talk we will examine the current state of the Flink Runner. Beam’s Runners manage the translation of the Beam API into the backend API. The Beam project itself has made an effort to summarize the capabilities of each Runner to provide an overview of the supported API concepts. From all open sources backends, Flink is currently the Runner which supports the most features. We will look at the supported Beam features and their counterpart in Flink. Further, we will look at potential improvements and upcoming features of the Flink Runner.

Javier Lopez_Mihail Vieru - Flink in Zalando's World of Microservices - Flink...
http://flink-forward.org/kb_sessions/flink-in-zalandos-world-of-microservices/
In this talk we present Zalando’s microservices architecture, introduce Saiki – our next generation data integration and distribution platform on AWS and show how we employ stream processing with Apache Flink for near-real time business intelligence.
Zalando is one of the largest online fashion retailers in Europe. In order to secure our future growth and remain competitive in this dynamic market, we are transitioning from a monolithic to a microservices architecture and from a hierarchical to an agile organization.
We first have a look at how business intelligence processes have been working inside Zalando for the last years and present our current approach – Saiki. It is a scalable, cloud-based data integration and distribution infrastructure that makes data from our many microservices readily available for analytical teams.
We no longer live in a world of static data sets, but are instead confronted with endless streams of events that constantly inform us about relevant happenings from all over the enterprise. The processing of these event streams enables us to do near-real time business intelligence. In this context we have evaluated Apache Flink vs. Apache Spark in order to choose the right stream processing framework. Given our requirements, we decided to use Flink as part of our technology stack, alongside with Kafka and Elasticsearch.
With these technologies we are currently working on two use cases: a near real-time business process monitoring solution and streaming ETL.
Monitoring our business processes enables us to check if technically the Zalando platform works. It also helps us analyze data streams on the fly, e.g. order velocities, delivery velocities and to control service level agreements.
On the other hand, streaming ETL is used to relinquish resources from our relational data warehouse, as it struggles with increasingly high loads. In addition to that, it also reduces the latency and facilitates the platform scalability.
Finally, we have an outlook on our future use cases, e.g. near-real time sales and price monitoring. Another aspect to be addressed is to lower the entry barrier of stream processing for our colleagues coming from a relational database background.
Taking a look under the hood of Apache Flink's relational APIs.
Apache Flink features two APIs which are based on relational algebra, a SQL interface and the so-called Table API, which is a LINQ-style API available for Scala and Java. Relational APIs are interesting because they are easy to use and queries can be automatically optimized and translated into efficient runtime code. Flink offers both APIs for streaming and batch data sources. This talk takes a look under the hood of Flink’s relational APIs. The presentation shows the unified architecture to handle streaming and batch queries and explain how Flink translates queries of both APIs into the same representation, leverages Apache Calcite to optimize them, and generates runtime code for efficient execution. Finally, the slides discuss potential improvements and give an outlook for future extensions and features.
Beaming flink to the cloud @ netflix ff 2016-monal-daxini
Netflix is a data driven company and we process over 700 billion streaming events per day with at-least once processing semantics in the cloud. To enable extracting intelligence from this unbounded stream easily we are building Stream Processing as a Service (SPaaS) infrastructure so that the user can focus on extracting value and not have to worry about boilerplate infrastructure and scale.
We will share our experience in building a scalable SPaaS using Flink, Apache Beam and Kafka as the foundation layer to process over 1.3 PB of event data without service disruption.

Many use cases in the telecommunication industry require producing counters, quality metrics, and alarms in a streaming fashion with very low latency. Most of this metrics are only valuable when they’re made available as soon as the associated events happened. In our company we are looking for a system able to produce this kind of real-time indicator, which must handle massive amounts of data (400,000 eps) with often peak loads (like New Year’s Eve) or out-of-order events like massive network disorder. Low latency and flexible window management with specific watermark emission are also a must-haves. Heterogeneous format, multiple flow correlation, and the possibility of late data arrival are other challenges. Flink being already widely used at Bouygues Telecom for real-time data integration, its features made it the evident candidate for the future System. In this talk, we'll present a real use case of streaming analytics using Flink, Kafka & HBase along with other legacy systems.
Ted Dunning-Faster and Furiouser- Flink Drift
http://flink-forward.org/kb_sessions/faster-and-furiouser-flink-drift/
Not long ago, we had the opportunity to test Apache Flink to see just how fast it would go on a moderately realistic task with fast hardware and with a good streaming transport layer underneath. Our goal was not so much careful comparison with other software, but flat-out speed, Flink against Flink. In the process, we learned a lot about what it takes to go fast. Some of the lessons were ones that we had “learned” a number of times before: – the bottleneck isn’t where you thought it was – copying data is expensive – context switches are expensive – measure twice, cut once But there were some real surprises along the way. The really important knobs weren’t quite what people say you should turn. One of the biggest surprises was the degree to which high performance libraries have threading built into them which makes the actual concurrrency much higher than the apparent concurrency. The result was that at least one cluster parameter needed to be adjusted by 30x to get real
Hadoop summit - Scaling Uber’s Real-Time Infra for Trillion Events per Day
Building data pipelines is pretty hard! Building a multi-datacenter active-active real time data pipeline for multiple classes of data with different durability, latency and availability guarantees is much harder.
Real time infrastructure powers critical pieces of Uber (think Surge) and in this talk we will discuss our architecture, technical challenges, learnings and how a blend of open source infrastructure (Apache Kafka and Samza) and in-house technologies have helped Uber scale.
Malo Denielou - No shard left behind: Dynamic work rebalancing in Apache Beam
http://flink-forward.org/kb_sessions/no-shard-left-behind-dynamic-work-rebalancing-in-apache-beam/
The Apache Beam (incubating) programming model is designed to support several advanced data processing features such as autoscaling and dynamic work rebalancing. In this talk, we will first explain how dynamic work rebalancing not only provides a general and robust solution to the problem of stragglers in traditional data processing pipelines, but also how it allows autoscaling to be truly effective. We will then present how dynamic work rebalancing works as implemented in Google Cloud Dataflow and which path other Apache Beam runners link Apache Flink can follow to benefit from it.

Jim Dowling - Multi-tenant Flink-as-a-Service on YARN
http://flink-forward.org/kb_sessions/multi-tenant-flink-as-a-service-on-yarn/
Since June 2016, Flink-as-a-service has been available to researchers and companies in Sweden from the Swedish ICT SICS Data Center at www.hops.site using the HopsWorks platform. Flink applications can be either deployed as jobs (batch or streaming) or written and run directly from Apache Zeppelin on YARN. Flink applications are run within a project on a YARN cluster with the novel property that Flink applications are metered and charged to projects. Projects are also securely isolated from each other and include support for project-specific Kafka topics that are protected from access by users that are not members of the project. Hopsworks is entirely UI-driven, is open-source, and Flink applications that include Kafka topics can be created in a few mouse clicks. In this talk we will discuss the challenges in building a metered version of Flink-as-a-Service for YARN, experiences with Flink-on-YARN, and some of the possibilities that Hopsworks opens up for building secure, multi-ten

In this hands on talk and demonstration I’ll give a very short introduction to stream processing and then dive into writing code and demonstrating the features in Apache Flink that make truly robust stream processing possible. We’ll focus on correctness and robustness in stream processing. During this live demo we’ll be developing a realtime analytics application and modifying it on the fly based on the topics we’re working though. We’ll exercise Flink’s unique features, demonstrate fault-recovery, clearly explain and demonstrate why Event Time is such an important concept in robust stateful stream processing and talk about and demonstrate the features you need in a stream processor in production. Some of the topics covered will be: – Stateful Stream Processing – Event Time vs. Processing Time – Fault tolerance – State management in the face of faults – Savepoints – Data re-processing – Planned downtime and upgrades

Zoltán Zvara - Advanced visualization of Flink and Spark jobs
http://flink-forward.org/kb_sessions/advanced-visualization-of-flink-and-spark-jobs/
Understanding the physical plan of a big data application is often crucial for tracking down bottlenecks and faulty behavior. Flink and Spark although offering useful Web UI components for monitoring and understanding the logical plan of the jobs, both lack a tool that helps to understand the physical plan of the scheduler and the possibility to monitor execution at a very low level, along with the communication that occur between parallel vertex instances. We propose a tool that allows users to real-time monitor and later to replay, examine job executions on any cluster currently supported by Flink or Spark. The tool also offers monitoring of the distribution of keys in a data stream and can lead to optimizing data partitioning across parallel subtasks in the future.
Analyzing Petabyte Scale Financial Data with Apache Pinot and Apache Kafka | ...
At Stripe, we operate a general ledger modeled as double-entry bookkeeping for all financial transactions. Warehousing such data is challenging due to its high volume and high cardinality of unique accounts.
aFurthermore, it is financially critical to get up-to-date, accurate analytics over all records. Due to the changing nature of real time transactions, it is impossible to pre-compute the analytics as a fixed time series. We have overcome the challenge by creating a real time key-value store inside Pinot that can sustain half million QPS with all the financial transactions.
We will talk about the details of our solution and the interesting technical challenges faced.
Fundamentals of Stream Processing with Apache Beam, Tyler Akidau, Frances Perry
Apache Beam (unified Batch and strEAM processing!) is a new Apache incubator project. Originally based on years of experience developing Big Data infrastructure within Google (such as MapReduce, FlumeJava, and MillWheel), it has now been donated to the OSS community at large.
Come learn about the fundamentals of out-of-order stream processing, and how Beam’s powerful tools for reasoning about time greatly simplify this complex task. Beam provides a model that allows developers to focus on the four important questions that must be answered by any stream processing pipeline:
What results are being calculated?
Where in event time are they calculated?
When in processing time are they materialized?
How do refinements of results relate?
Furthermore, by cleanly separating these questions from runtime characteristics, Beam programs become portable across multiple runtime environments, both proprietary (e.g., Google Cloud Dataflow) and open-source (e.g., Flink, Spark, et al).

The talk will also examine how to deal with issues of data retention, throttling, and persistence, finishing with recommendations for how to use these sandbox environments to rapidly prototype and test new features and fixes.
Apache Flink 101 - the rise of stream processing and beyond
Apache Flink is the most popular and widely adopted streaming processing framework, powering real time stream event computations at extremely large scale in companies like Uber, Lyft, AWS, Alibaba, Pinterest, Splunk, Yelp, etc.
In this talk, we will go over use cases and basic (yet hard to achieve!) requirements of stream processing, and how Flink fills the gaps and stands out with some of its unique core building blocks, like pipelined execution, native event time support, state support, and fault tolerance.
We will also take a look at how Flink is going beyond stream processing into areas like unified data processing, enterprise intergration, AI/machine learning (especially online ML), and serverless computation, and how Flink fits with its distinct value.

This session will provide an overview of the use of Kafka at Microsoft, and then deep dive into Siphon. We will describe an important business scenario and talk about the technical details of the system in the context of that scenario. We will also cover the design and implementation of the service, the scale, and real world production experiences from operating the service in the Microsoft cloud environment.
Bravo Six, Going Realtime. Transitioning Activision Data Pipeline to Streamin...
Activision Data team has been running a data pipeline for a variety of Activision games for many years. Historically we used a mix of micro-batch microservices coupled with classic Big Data tools like Hadoop and Hive for ETL. As a result, it could take up to 4-6 hours for data to be available to the end customers.
In the last few years, the adoption of data in the organization skyrocketed. We needed to de-legacy our data pipeline and provide near-realtime access to data in order to improve reporting, gather insights faster, power web and mobile applications. I want to tell a story about heavily leveraging Kafka Streams and Kafka Connect to reduce the end latency to minutes, at the same time making the pipeline easier and cheaper to run. We were able to successfully validate the new data pipeline by launching two massive games just 4 weeks apart.

Flink Forward Berlin 2017 Keynote: Ferd Scheepers - Taking away customer fric...
As many industries, banking is undergoing a fundamental change because of the software revolution. No longer are banks competing only on interest rates and having the best traders, these days customer experience and having the best engineers are the focus. In this changing world, banks compete with new start-ups, the so-called Fintechs, and with large platform organisations such as Google, Facebook and Apple. At ING, we believe that staying ahead of the game means changing how we interact with our customers, no longer a traditional model of waiting for the customers to come to the bank through our website or apps, but to actively reach out to the customer with information that is relevant to him or her in order to make their financial life frictionless. Many of these changes are driven by reacting to all events that are relevant to the customer, and using streaming analytics to be able to reach out to the customer in milliseconds after the event occurs. Apache Flink is key for ING to achieve this. This presentation addresses how ING approaches the challenge, the role that Apache Flink plays, and the consequences regulations have on how we work with Open Source in general, and with Apache Flink (and data Artisans) in particular. This keynote takes place at Kino 3.
Kafka, Killer of Point-to-Point Integrations, Lucian Lita
With 60+ products and over 24% of the US GDP flowing through it, system integration is a tough problem for Intuit. Seasonality, scale, and massive peaks in products like TurboTax, QuickBooks, and Mint.com add extra layers of difficulty when building shared data services around transaction and user graphs, clickstream processing, a/b testing, and personalization. To reduce complexity and latency, we’ve implemented Kafka as the backbone across these data services. This allows us to asynchronously trigger relevant processing, elegantly scaling up and down as needed around peaks, all without the need for point-to-point integrations.
In this talk, we share what we’ve learned about Kafka at Intuit and describe our data services architecture. We found that Kafka is invaluable in achieving a scalable, clean architecture, allowing engineering teams to focus less on integration and more on product development.

Siphon - Near Real Time Databus Using Kafka, Eric Boyd, Nitin Kumar
Siphon is a highly available and reliable distributed pub/sub system built using Apache Kafka. It is used to publish, discover and subscribe to near real-time data streams for operational and product intelligence. Siphon is used as a “Databus” by a variety of producers and subscribers in Microsoft, and is compliant with security and privacy requirements. It has a built-in Auditing and Quality control. This session will provide an overview of the use of Kafka at Microsoft, and then deep dive into Siphon. We will describe an important business scenario and talk about the technical details of the system in the context of that scenario. We will also cover the design and implementation of the service, the scale, and real world production experiences from operating the service in the Microsoft cloud environment.
Bravo Six, Going Realtime. Transitioning Activision Data Pipeline to Streamin...
Activision Data team has been running a data pipeline for a variety of Activision games for many years. Historically we used a mix of micro-batch microservices coupled with classic Big Data tools like Hadoop and Hive for ETL. As a result, it could take up to 4-6 hours for data to be available to the end customers.
In the last few years, the adoption of data in the organization skyrocketed. We needed to de-legacy our data pipeline and provide near-realtime access to data in order to improve reporting, gather insights faster, power web and mobile applications. I want to tell a story about heavily leveraging Kafka Streams and Kafka Connect to reduce the end latency to minutes, at the same time making the pipeline easier and cheaper to run. We were able to successfully validate the new data pipeline by launching two massive games just 4 weeks apart.

As many industries, banking is undergoing a fundamental change because of the software revolution. No longer are banks competing only on interest rates and having the best traders, these days customer experience and having the best engineers are the focus. In this changing world, banks compete with new start-ups, the so-called Fintechs, and with large platform organisations such as Google, Facebook and Apple. At ING, we believe that staying ahead of the game means changing how we interact with our customers, no longer a traditional model of waiting for the customers to come to the bank through our website or apps, but to actively reach out to the customer with information that is relevant to him or her in order to make their financial life frictionless. Many of these changes are driven by reacting to all events that are relevant to the customer, and using streaming analytics to be able to reach out to the customer in milliseconds after the event occurs. Apache Flink is key for ING to achieve this. This presentation addresses how ING approaches the challenge, the role that Apache Flink plays, and the consequences regulations have on how we work with Open Source in general, and with Apache Flink (and data Artisans) in particular. This keynote takes place at Kino 3.
Kafka, Killer of Point-to-Point Integrations, Lucian Lita
With 60+ products and over 24% of the US GDP flowing through it, system integration is a tough problem for Intuit. Seasonality, scale, and massive peaks in products like TurboTax, QuickBooks, and Mint.com add extra layers of difficulty when building shared data services around transaction and user graphs, clickstream processing, a/b testing, and personalization. To reduce complexity and latency, we’ve implemented Kafka as the backbone across these data services. This allows us to asynchronously trigger relevant processing, elegantly scaling up and down as needed around peaks, all without the need for point-to-point integrations.
In this talk, we share what we’ve learned about Kafka at Intuit and describe our data services architecture. We found that Kafka is invaluable in achieving a scalable, clean architecture, allowing engineering teams to focus less on integration and more on product development.

Realizing the promise of portability with Apache Beam
The world of big data involves an ever changing field of players. Much as SQL stands as a lingua franca for declarative data analysis, Apache Beam (incubating) aims to provide a portable standard for expressing robust, out-of-order data processing pipelines in a variety of languages across a variety of platforms.
In this talk, I will:
Cover briefly the capabilities of the Beam model for data processing and integration with IOs, as well as the current state of the Beam ecosystem.
Discuss the benefits Beam provides regarding portability and ease-of-use.
Demo the same Beam pipeline running on multiple runners in multiple deployment scenarios (e.g. Apache Flink on Google Cloud, Apache Spark on AWS, Apache Apex on-premise).
Give a glimpse at some of the challenges Beam aims to address in the future.

Unified, Efficient, and Portable Data Processing with Apache Beam
Unbounded, unordered, global scale datasets are increasingly common in day-to-day business, and consumers of these datasets have detailed requirements for latency, cost, and completeness. Apache Beam defines a new data processing programming model that evolved from more than a decade of experience building Big Data infrastructure within Google, including MapReduce, FlumeJava, Millwheel, and Cloud Dataflow.
Apache Beam handles both batch and streaming use cases, offering a powerful, unified model. It neatly separates properties of the data from run-time characteristics, allowing pipelines to be portable across multiple run-time environments, both open source, including Apache Apex, Apache Flink, Apache Gearpump, Apache Spark, and proprietary. Finally, Beam's model enables newer optimizations, like dynamic work rebalancing and autoscaling, resulting in an efficient execution.
This talk will cover the basics of Apache Beam, touch on its evolution, and describe main concepts in its powerful programming model. We'll show how Beam unifies batch and streaming use cases, and show efficient execution in real-world scenarios. Finally, we'll demonstrate pipeline portability across Apache Apex, Apache Flink, Apache Spark and Google Cloud Dataflow in a live setting.

Large-Scale Stream Processing in the Hadoop Ecosystem
Large-Scale Stream Processing in the Hadoop Ecosystem
Large-Scale Stream Processing in the Hadoop Ecosystem - Hadoop Summit 2016
Distributed stream processing is one of the hot topics in big data analytics today. An increasing number of applications are shifting from traditional static data sources to processing the incoming data in real-time. Performing large scale stream analysis requires specialized tools and techniques which have become widely available in the last couple of years. This talk will give a deep, technical overview of the Apache stream processing landscape. We compare several frameworks including Flink , Spark, Storm, Samza and Apex. Our goal is to highlight the strengths and weaknesses of the individual systems in a project-neutral manner to help selecting the best tools for the specific applications. We will touch on the topics of API expressivity, runtime architecture, performance, fault-tolerance and strong use-cases for the individual frameworks. This talk is targeted towards anyone interested in streaming analytics either from user’s or contributor’s perspective. The attendees can expect to get a clear view of the available open-source stream processing architectures
Event-Driven Stream Processing and Model Deployment with Apache Kafka, Kafka ...
Talk from Kafka Summit San Francisco 2019 (https://kafka-summit.org/sessions/event-driven-model-serving-stream-processing-vs-rpc-kafka-tensorflow/). Video recording will be available for free on the Summit website.
Event-based stream processing is a modern paradigm to continuously process incoming data feeds, e.g. for IoT sensor analytics, payment and fraud detection, or logistics. Machine Learning / Deep Learning models can be leveraged in different ways to do predictions and improve the business processes. Either analytic models are deployed natively in the application or they are hosted in a remote model server. In the latter you combine stream processing with RPC / Request-Response paradigm instead of direct doing direct inference within the application. This talk discusses the pros and cons of both approaches and shows examples of stream processing vs. RPC model serving using Kubernetes, Apache Kafka, Kafka Streams, gRPC and TensorFlow Serving. The trade-offs of using a public cloud service like AWS or GCP for model deployment are also discussed and compared to local hosting for offline predictions directly “at the edge”.
Key takeaways
• Machine Learning / Deep Learning models can be used in different ways to do predictions. Scalability and loose coupling are important success factors
• Stream processing vs. RPC / Request-Response for model serving has many trade-offs – learn about alternatives and best practices for your different scenarios
• Understand the alternatives and trade-offs of model deployment in modern infrastructures like Kubernetes or Cloud Services like AWS or GCP
• See live demos with Java, gRPC, Apache Kafka, KSQL and TensorFlow Serving to understand the trade-offs

Apache Flink is a distributed stream processing framework that allows users to process and analyze data in real-time. At LinkedIn, we developed a fully managed stream processing platform on Flink running on K8s to power hundreds of stream processing pipelines in production. This platform is the backbone for other infra systems like Search, Espresso (internal document store) and feature management etc. We provide a rich authoring and testing environment which allows users to create, test, and deploy their streaming jobs in a self-serve fashion within minutes. Users can focus on their business logic, leaving the Flink platform to take care of management aspects such as split deployment, resource provisioning, auto-scaling, job monitoring, alerting, failure recovery and much more. In this talk, we will introduce the overall platform architecture, highlight the unique value propositions that it brings to stream processing at LinkedIn and share the experiences and lessons we have learned.
Evening out the uneven: dealing with skew in Flink
Flink Forward San Francisco 2022.
When running Flink jobs, skew is a common problem that results in wasted resources and limited scalability. In the past years, we have helped our customers and users solve various skew-related issues in their Flink jobs or clusters. In this talk, we will present the different types of skew that users often run into: data skew, key skew, event time skew, state skew, and scheduling skew, and discuss solutions for each of them. We hope this will serve as a guideline to help you reduce skew in your Flink environment.

Flink Forward San Francisco 2022.
To improve Amazon Alexa experiences and support machine learning inference at scale, we built an automated end-to-end solution for incremental model building or fine-tuning machine learning models through continuous learning, continual learning, and/or semi-supervised active learning. Customer privacy is our top concern at Alexa, and as we build solutions, we face unique challenges when operating at scale such as supporting multiple applications with tens of thousands of transactions per second with several dependencies including near-real time inference endpoints at low latencies. Apache Flink helps us transform and discover metrics in near-real time in our solution. In this talk, we will cover the challenges that we faced, how we scale the infrastructure to meet the needs of ML teams across Alexa, and go into how we enable specific use cases that use Apache Flink on Amazon Kinesis Data Analytics to improve Alexa experiences to delight our customers while preserving their privacy.

Introducing BinarySortedMultiMap - A new Flink state primitive to boost your ...
Flink Forward San Francisco 2022.
Probably everyone who has written stateful Apache Flink applications has used one of the fault-tolerant keyed state primitives ValueState, ListState, and MapState. With RocksDB, however, retrieving and updating items comes at an increased cost that you should be aware of. Sometimes, these may not be avoidable with the current API, e.g., for efficient event-time stream-sorting or streaming joins where you need to iterate one or two buffered streams in the right order. With FLIP-220, we are introducing a new state primitive: BinarySortedMultiMapState. This new form of state offers you to (a) efficiently store lists of values for a user-provided key, and (b) iterate keyed state in a well-defined sort order. Both features can be backed efficiently by RocksDB with a 2x performance improvement over the current workarounds. This talk will go into the details of the new API and its implementation, present how to use it in your application, and talk about the process of getting it into Flink.

Autoscaling Flink with Reactive Mode
Flink Forward San Francisco 2022.
Resource Elasticity is a frequently requested feature in Apache Flink: Users want to be able to easily adjust their clusters to changing workloads for resource efficiency and cost saving reasons. In Flink 1.13, the initial implementation of Reactive Mode was introduced, later releases added more improvements to make the feature production ready. In this talk, we’ll explain scenarios to deploy Reactive Mode to various environments to achieve autoscaling and resource elasticity. We’ll discuss the constraints to consider when planning to use this feature, and also potential improvements from the Flink roadmap. For those interested in the internals of Flink, we’ll also briefly explain how the feature is implemented, and if time permits, conclude with a short demo.

Flink Forward San Francisco 2022.
Flink consumers read from Kafka as a scalable, high throughput, and low latency data source. However, there are challenges in scaling out data streams where migration and multiple Kafka clusters are required. Thus, we introduced a new Kafka source to read sharded data across multiple Kafka clusters in a way that conforms well with elastic, dynamic, and reliable infrastructure. In this presentation, we will present the source design and how the solution increases application availability while reducing maintenance toil. Furthermore, we will describe how we extended the existing KafkaSource to provide mechanisms to read logical streams located on multiple clusters, to dynamically adapt to infrastructure changes, and to perform transparent cluster migrations and failover.

One sink to rule them all: Introducing the new Async Sink
Flink Forward San Francisco 2022.
Next time you want to integrate with a new destination for a demo, concept or production application, the Async Sink framework will bootstrap development, allowing you to move quickly without compromise. In Flink 1.15 we introduced the Async Sink base (FLIP-171), with the goal to encapsulate common logic and allow developers to focus on the key integration code. The new framework handles things like request batching, buffering records, applying backpressure, retry strategies, and at least once semantics. It allows you to focus on your business logic, rather than spending time integrating with your downstream consumers. During the session we will dive deep into the internals to uncover how it works, why it was designed this way, and how to use it. We will code up a new sink from scratch and demonstrate how to quickly push data to a destination. At the end of this talk you will be ready to start implementing your own Flink sink using the new Async Sink framework.

Tuning Apache Kafka Connectors for Flink.pptx
Flink Forward San Francisco 2022.
In normal situations, the default Kafka consumer and producer configuration options work well. But we all know life is not all roses and rainbows and in this session we’ll explore a few knobs that can save the day in atypical scenarios. First, we'll take a detailed look at the parameters available when reading from Kafka. We’ll inspect the params helping us to spot quickly an application lock or crash, the ones that can significantly improve the performance and the ones to touch with gloves since they could cause more harm than benefit. Moreover we’ll explore the partitioning options and discuss when diverging from the default strategy is needed. Next, we’ll discuss the Kafka Sink. After browsing the available options we'll then dive deep into understanding how to approach use cases like sinking enormous records, managing spikes, and handling small but frequent updates.. If you want to understand how to make your application survive when the sky is dark, this session is for you!

The Current State of Table API in 2022
Flink Forward San Francisco 2022.
The Table API is one of the most actively developed components of Flink in recent time. Inspired by databases and SQL, it encapsulates concepts many developers are familiar with. It can be used with both bounded and unbounded streams in a unified way. But from afar it can be difficult to keep track of what this API is capable of and how it relates to Flink's other APIs. In this talk, we will explore the current state of Table API. We will show how it can be used as a batch processor, a changelog processor, or a streaming ETL tool with many built-in functions and operators for deduplicating, joining, and aggregating data. By comparing it to the DataStream API we will highlight differences and elaborate on when to use which API. We will demonstrate hybrid pipelines in which both APIs interact with one another and contribute their unique strengths. Finally, we will take a look at some of the most recent additions as a first step to stateful upgrades.

Processing Semantically-Ordered Streams in Financial Services
Flink Forward San Francisco 2022.
What if my data is already in order? Stream Processing has given us an elegant and powerful solution for running analytic queries and logic over high volumes of continuously arriving data. However, in both Apache Flink and Apache Beam, the notion of time-ordering is baked in at a very low level, making it difficult to express computations that are interested in a semantic-, rather than time-ordering of the data. In financial services, what often matters the most about the data moving between systems is not when the data was created, but in what order, to the extent that many institutions engineer a global sequencing over all data entering and produced by their systems to achieve complete determinism. How, then, can financial institutions and others best employ Stream Processing on streams of data that are already ordered? I will cover various techniques that can make this work, as well as seek input from the community on how Flink might be improved to better support these use-cases.

Tame the small files problem and optimize data layout for streaming ingestion...
Flink Forward San Francisco 2022.
In modern data platform architectures, stream processing engines such as Apache Flink are used to ingest continuous streams of data into data lakes such as Apache Iceberg. Streaming ingestion to iceberg tables can suffer by two problems (1) small files problem that can hurt read performance (2) poor data clustering that can make file pruning less effective. To address those two problems, we propose adding a shuffling stage to the Flink Iceberg streaming writer. The shuffling stage can intelligently group data via bin packing or range partition. This can reduce the number of concurrent files that every task writes. It can also improve data clustering. In this talk, we will explain the motivations in details and dive into the design of the shuffling stage. We will also share the evaluation results that demonstrate the effectiveness of smart shuffling.

Batch Processing at Scale with Flink & Iceberg
Flink Forward San Francisco 2022.
Goldman Sachs's Data Lake platform serves as the firm's centralized data platform, ingesting 140K (and growing!) batches per day of Datasets of varying shape and size. Powered by Flink and using metadata configured by platform users, ingestion applications are generated dynamically at runtime to extract, transform, and load data into centralized storage where it is then exported to warehousing solutions such as Sybase IQ, Snowflake, and Amazon Redshift. Data Latency is one of many key considerations as producers and consumers have their own commitments to satisfy. Consumers range from people/systems issuing queries, to applications using engines like Spark, Hive, and Presto to transform data into refined Datasets. Apache Iceberg allows our applications to not only benefit from consistency guarantees important when running on eventually consistent storage like S3, but also allows us the opportunity to improve our batch processing patterns with its scalability-focused features.

Maximilian Michels - Flink and Beam
- 1. Flink and Beam: Current State & Roadmap Maximilian Michels PMC Apache Flink and Apache Beam FlinkForward 2016 Apache Flink® Apache Beam (incubating)
- 2. 2 Google Cloud Dataflow On Top of Apache Flink® Last year’s talk: This year’s talk: Apache Flink® and Apache Beam: Current State & Roadmap What happened?
- 3. Two projects, one idea • Dec 2014 Google releases the Cloud Dataflow Java SDK • Feb 2016 Cloud Dataflow Java SDK becomes Apache Beam 3 MapReduce BigTable DremelColossus FlumeMegastoreSpanner PubSub Millwheel Apache Beam Google Cloud Dataflow Taken from the official Beam material
- 4. Apache Beam (incubating) • Jan 2016 Google proposes project to the Apache incubator • Feb 2016 Project enters incubation • Jun 2016 Apache Beam 0.1.0-incubating released • Jul 2016 Apache Beam 0.2.0-incubating released 4 Dataflow Java 1.x Apache Beam Java 0.x Apache Beam Java 2.x Bug Fix Feature Breaking Change
- 5. The Dataflow/Beam Model • 2004 MapReduce • 2010 Flume Java (Beam’s API) • 2013 MillWheel (Watermarks, exactly-once, Windows) • Sep 2015 Dataflow Model published at VLDB • Nov 2015 Apache Flink 0.10.0 DataStream API features Event Time in line with the Dataflow model 5
- 6. Beam Runners • A Runner ports Beam code to a backend • A Runner’s concern is • a) translation • b) runtime execution • Runners available: • Google Cloud Dataflow • Apache Flink • Apache Spark • In Development: Gearpump, Apache Apex 6 Beam Model: Fn Runners Apache Flink Apache Spark Beam Model: Pipeline Construction Other LanguagesBeam Java Beam Python Execution Execution Cloud Dataflow Execution Taken from the official Beam material
- 7. Flink Runner - Status Quo • Stable: 0.2.0-incubating • Powered by Flink 1.0.3 • Development: 0.3.0-incubating-SNAPSHOT • Powered by Flink 1.1.2 • Changes coming in regularly, use the snapshot version to get the latest features 7
- 8. Evolution of the Flink Runner 2014 Dec • Google Cloud Dataflow SDK released 2015 Jan • Initial commit and drafting Mar • Batch support without Windows Dec • Streaming support with Watermarks and Windows 8 2016 Mar • Contribution to Apache Beam May • Parallel and checkpointed sources in streaming • Batch support with Windows and Side Inputs • RunnableOnService for batch Aug • Side Inputs for streaming • RunnableOnService for streaming
- 9. Batched vs Streamed Execution • Batched Execution • Built on top of the DataSet API • Supports only bounded sources • Managed Memory • Streamed Execution • Built on top of the DataStream API • Supports bounded and unbounded sources • Watermark support which leverages full Dataflow Model • Checkpointing • When to pick which? If undecided, just let the Runner decide 9
- 10. The Flink Runner’s Strength • Backed by a runtime which is streaming and batch aware • Embeds and reuses Beam logic whenever possible • Window and Triggering • Source API • State Internals / Checkpointing • Whenever possible, translate primitive transforms • Integration with Beam’s RunnableOnService tests (batch/ streaming) 10
- 11. Capability Matrix • Compares Runners with the reference model • What results are being calculated? • Where in event time? • When in processing time? • How do refinements of results relate? 11 For more information see http://beam.incubator.apache.org/learn/runners/capability-matrix/
- 12. What 12
- 13. Where 13
- 14. When 14
- 15. How 15
- 16. So we’re good? • Flink Runner currently the most advanced Runner which is backed by an open-source engine • Does that mean the Flink Runner is perfect? 16
- 17. Roadmap Flink Runner • Side Input streaming: size restrictions • Integrate with new PipelineResult • Dynamic Scaling • Incremental Checkpointing • Connectors (Kafka 8/9, Cassandra, Elasticsearch, RabbitMQ, Redis, NiFi, Kinesis) • Libraries (Gelly, CEP, Storm Compatibility, ML) • Performance testing • Bug fixes 17
- 18. Apache Flink Features powering the Runner • Streaming • Checkpointing / Savepoints • State backends • Batch • Pipelined execution • Managed Memory • High Availability • Flink’s native sources / sinks 18
- 19. Demo • Develop a Beam program with the Flink Runner • Monitor applications using the web interface • Handle failures by restoring from checkpointed state • Create a Savepoint, stop the Beam program, resume execution from it 19
- 20. Thank you for your attention!
