Replicating Relational Database Binary Logs to Kafka into Hadoop, Spark, Zeppelin, and Elasticsearch via StreamSets. Presented at the Apache Kafka DC meetup on 7 April 2016.
1. Spark Streaming uses Kafka receivers to process data from Kafka in batches at regular intervals. The receivers divide the streams into blocks and write them to Spark's block manager.
2. When processing batches, Spark retrieves the blocks from the block manager and runs jobs on the RDDs created from the blocks.
3. Reliable receivers are needed to handle failures of receivers or the driver, to prevent data loss. The Spark package provides a low-level Kafka receiver implementation that reliably handles offsets and failures.
Spark Streaming can be used to process streaming data from Kafka in real-time. There are two main approaches - the receiver-based approach where Spark receives data from Kafka receivers, and the direct approach where Spark directly reads data from Kafka. The document discusses using Spark Streaming to process tens of millions of transactions per minute from Kafka for an ad exchange system. It describes architectures where Spark Streaming is used to perform real-time aggregations and update databases, as well as save raw data to object storage for analytics and recovery. Stateful processing with mapWithState transformations is also demonstrated to update Cassandra in real-time.
The document discusses new features in Java 8 including lambda expressions, method references, functional interfaces, default methods, streams, Optional class, and the new date/time API. It provides examples and explanations of how these features work, common use cases, and how they improve functionality and code readability in Java. Key topics include lambda syntax, functional interfaces, default interface methods, Stream API operations like filter and collect, CompletableFuture for asynchronous programming, and the replacement of java.util.Date with the new date/time classes.
This document discusses two approaches for receiving data from Kafka in Spark Streaming - the receiver-based approach and direct approach. The receiver-based approach uses Kafka's high-level API and enables exactly-once processing semantics but requires writing to WAL. The direct approach fetches offsets manually, provides simplified parallelism with 1:1 mapping of partitions, and more efficiency without needing WAL, but does not guarantee exactly-once processing. It also covers how to set up a Spark Streaming application with Kafka, including library dependencies, Kafka consumer properties, subscribing to topics, and location strategies.
This document provides tips for developing applications with ScyllaDB. It recommends limiting request concurrency by using semaphores or driver configuration options. It discusses strategies for retrying requests, including ensuring idempotency and introducing delays through exponential backoff. It also recommends using prepared statements, the right load balancing policy, and testing retry strategies before production.

(Bill Bejeck, Confluent) Kafka Summit SF 2018
Apache Kafka added a powerful stream processing library in mid-2016, Kafka Streams, which runs on top of Apache Kafka. The community has embraced Kafka Streams with many early adopters, and the adoption rate continues to grow. Large to mid-size organizations have come to rely on Kafka Streams in their production environments. Kafka Streams has many advanced features to make applications more robust.
The point of this presentation is to show users of Kafka Streams some of the latest and greatest features, as well as some that may be advanced, that can make streams applications more resilient. The target audience for this talk are those users already comfortable writing Kafka Streams applications and want to go from writing their first proof-of-concept applications to writing robust applications that can withstand the rigor that running in a production environment demands.
The talk will be a technical deep dive covering topics like:
-Best practices on configuring a Kafka Streams application
-How to meet production SLAs by minimizing failover and recovery times: configuring standby tasks and the pros and cons of having standby replicas for local state
-How to improve resiliency and 24×7 operability: the use of different configurable error handlers, callbacks and how they can be used to see what’s going on inside the application
-How to achieve efficient scalability: a thorough review of the relationship between the number of instances, threads and state stores and how they relate to each other
While this is a technical deep dive, the talk will also present sample code so that attendees can view the concepts discussed in practice. Attendees of this talk will walk away with a deeper understanding of how Kafka Streams works, and how to make their Kafka Streams applications more robust and efficient. There will be a mix of discussion.
Spark Streaming has supported Kafka since it's inception, but a lot has changed since those times, both in Spark and Kafka sides, to make this integration more fault-tolerant and reliable.Apache Kafka 0.10 (actually since 0.9) introduced the new Consumer API, built on top of a new group coordination protocol provided by Kafka itself.
So a new Spark Streaming integration comes to the playground, with a similar design to the 0.8 Direct DStream approach. However, there are notable differences in usage, and many exciting new features. In this talk, we will cover what are the main differences between this new integration and the previous one (for Kafka 0.8), and why Direct DStreams have replaced Receivers for good. We will also see how to achieve different semantics (at least one, at most one, exactly once) with code examples.
Finally, we will briefly introduce the usage of this integration in Billy Mobile to ingest and process the continuous stream of events from our AdNetwork.

Stream Processing using Apache Spark and Apache KafkaAbhinav Singh
This document provides an agenda for a session on Apache Spark Streaming and Kafka integration. It includes an introduction to Spark Streaming, working with DStreams and RDDs, an example of word count streaming, and steps for integrating Spark Streaming with Kafka including creating topics and producers. The session will also include a hands-on demo of streaming word count from Kafka using CloudxLab.
Gobblin on AWS allows running Gobblin data integration jobs on AWS infrastructure. It uses auto scaling groups to dynamically scale worker nodes and runs the Gobblin master in another auto scaling group. Network storage is provided by EFS. Gobblin as a Service will build on this to provide a fully managed service, adding monitoring, a UI, and job configuration storage in S3. It will also support additional cloud platforms and continuous execution of jobs.
Real-time streaming and data pipelines with Apache KafkaJoe Stein
Get up and running quickly with Apache Kafka http://kafka.apache.org/
* Fast * A single Kafka broker can handle hundreds of megabytes of reads and writes per second from thousands of clients.
* Scalable * Kafka is designed to allow a single cluster to serve as the central data backbone for a large organization. It can be elastically and transparently expanded without downtime. Data streams are partitioned and spread over a cluster of machines to allow data streams larger than the capability of any single machine and to allow clusters of co-ordinated consumers
* Durable * Messages are persisted on disk and replicated within the cluster to prevent data loss. Each broker can handle terabytes of messages without performance impact.
* Distributed by Design * Kafka has a modern cluster-centric design that offers strong durability and fault-tolerance guarantees.
Performance Analysis and Optimizations for Kafka Streams ApplicationsGuozhang Wang
High-speed and low footprint data stream processing is high in demand for Kafka Streams applications. However, how to write an efficient streaming application using the Streams DSL has been asked by many users in the past since it requires some deep knowledge about Kafka Streams internals. In this talk, I will talk about how to analyze your Kafka Streams applications, target performance bottlenecks and unnecessary storage costs, and optimize your application code accordingly using the Streams DSL.
In addition, I will talk about the new optimization framework that we have been developed inside Kafka Streams since the 2.1 release which replaced the in-place translation of the Streams DSL into a comprehensive process composed of streams topology compilation and rewriting phases, with a focus on reducing various storage footprints of Streams applications, such as state stores, internal topics etc.
1) The document proposes making a key-value storage system (CDP KVS) 10 times more scalable to support real-time data delivery.
2) Three ideas are presented: using an alternative distributed KVS, implementing a storage hierarchy on the existing KVS, and shipping edit logs to indexed archives.
3) The storage hierarchy approach of partitioning, compressing, and writing data to DynamoDB in batches is selected as it improves write performance and reduces storage costs while remaining stateless.
(Nina Hanzlikova, Zalando) Kafka Summit SF 2018
My team at Zalando fell in love with KStreams and their programming model straight out of the gate. However, as a small team of developers, building out and supporting our infrastructure while still trying to deliver solutions for our business has not always resulted in a smooth journey.
Can a small team of a couple of developers run their own Kafka infrastructure confidently and still spend most of their time developing code?
In this talk, we will dive into some of the problems we experienced while running Kafka brokers and Kafka Streams applications, as well as the consultations we had with other teams around this matter. We will outline some of the pragmatic decisions we made regarding backups, monitoring and operations to minimize our time spent administering our Kafka brokers and various stream applications.
Kafka on ZFS: Better Living Through Filesystems confluent
(Hugh O'Brien, Jet.com) Kafka Summit SF 2018
You’re doing disk IO wrong, let ZFS show you the way. ZFS on Linux is now stable. Say goodbye to JBOD, to directories in your reassignment plans, to unevenly used disks. Instead, have 8K Cloud IOPS for $25, SSD speed reads on spinning disks, in-kernel LZ4 compression and the smartest page cache on the planet. (Fear compactions no more!)
Learn how Jet’s Kafka clusters squeeze every drop of disk performance out of Azure, all completely transparent to Kafka.
-Striping cheap disks to maximize instance IOPS
-Block compression to reduce disk usage by ~80% (JSON data)
-Instance SSD as the secondary read cache (storing compressed data), eliminating >99% of disk reads and safe across host redeployments
-Upcoming features: Compressed blocks in memory, potentially quadrupling your page cache (RAM) for free
We’ll cover:
-Basic Principles
-Adapting ZFS for cloud instances (gotchas)
-Performance tuning for Kafka
-Benchmarks
Structured Streaming provides a scalable and fault-tolerant stream processing framework on Spark SQL. It allows users to write streaming jobs using simple batch-like SQL queries that Spark will automatically optimize for efficient streaming execution. This includes handling out-of-order and late data, checkpointing to ensure fault-tolerance, and providing end-to-end exactly-once guarantees. The talk discusses how Structured Streaming represents streaming data as unbounded tables and executes queries incrementally to produce streaming query results.
Build Real-Time Streaming ETL Pipelines With Akka Streams, Alpakka And Apache...Lightbend
Things were easier when all our data used to be offline, analyzed overnight in batches. Now our data is online, in motion, and generated constantly. For architects, developers and their businesses, this means that there is an urgent need for tools and applications that can deliver real-time (or near real-time) streaming ETL capabilities.
In this session by Konrad Malawski, author, speaker and Senior Akka Engineer at Lightbend, you will learn how to build these streaming ETL pipelines with Akka Streams, Alpakka and Apache Kafka, and why they matter to enterprises that are increasingly turning to streaming Fast Data applications.
Taming GC Pauses for Humongous Java Heaps in Spark Graph Computing-(Eric Kacz...Spark Summit
The document discusses tuning the Garbage First (G1) garbage collector in Java 8 to reduce garbage collection pauses for large heaps used in Spark graph computing workloads. It was found that the default G1 settings resulted in lengthy full garbage collections over 100 seconds. After analyzing the garbage collection logs, the main issue was identified as the concurrent marking phase not completing before a full collection was needed. Increasing the number of concurrent marking threads from 8 to 20 addressed this by speeding up the concurrent phase. With this tuning, no full collections occurred and total stop-the-world pause time was reduced to under a minute, a significant improvement over the original implementation.
Show Me Kafka Tools That Will Increase My Productivity! (Stephane Maarek, Dat...confluent
In the Apache Kafka world, there is such a great diversity of open source tools available (I counted over 50!) that it’s easy to get lost. Over the years I have dealt with Kafka, I have learned to particularly enjoy a few of them that save me a tremendous amount of time over performing manual tasks. I will be sharing my experience and doing live demos of my favorite Kafka tools, so that you too can hopefully increase your productivity and efficiency when managing and administering Kafka. Come learn about the latest and greatest tools for CLI, UI, Replication, Management, Security, Monitoring, and more!
Introducing Exactly Once Semantics To Apache KafkaApurva Mehta
Here are slides from my talk on introducing exactly once semantics to Apache Kafka. The talk was given at the Kafka Summit NYC, 8 May 2017.
The slides dive into the design of transactions in Apache Kafka.
(Randall Hauch, Confluent) Kafka Summit SF 2018
The Kafka Connect framework makes it easy to move data into and out of Kafka, and you want to write a connector. Where do you start, and what are the most important things to know? This is an advanced talk that will cover important aspects of how the Connect framework works and best practices of designing, developing, testing and packaging connectors so that you and your users will be successful. We’ll review how the Connect framework is evolving, and how you can help develop and improve it.
Event sourcing - what could possibly go wrong ? Devoxx PL 2021Andrzej Ludwikowski
Yet another presentation about Event Sourcing? Yes and no. Event Sourcing is a really great concept. Some could say it’s a Holy Grail of the software architecture. I might agree with that, while remembering that everything comes with a price. This session is a summary of my experience with ES gathered while working on 3 different commercial products. Instead of theoretical aspects, I will focus on possible challenges with ES implementation. What could explode (very often with delayed ignition)? How and where to store events effectively? What are possible schema evolution solutions? How to achieve the highest level of scalability and live with eventual consistency? And many other interesting topics that you might face when experimenting with ES.
Fluentd is a log collection tool that is well-suited for container environments. It allows for flexible log collection from containers through its variety of input plugins. Logs can be aggregated and buffered by Fluentd before being sent to output destinations like Elasticsearch. This addresses problems with traditional log collection in container environments by decoupling log collection from applications and making the infrastructure more scalable and reliable.
This summary provides an overview of the lightning talks presented at the NetflixOSS Open House:
- Jordan Zimmerman from Netflix presented on several NetflixOSS projects he works on including Curator, a Java library that makes using ZooKeeper easier, and Blitz4j, an asynchronous logging library that improves performance over Log4j.
- Additional talks covered Eureka, a REST service for discovering middle-tier services; Ribbon for load balancing between middle-tier instances; Archaius for dynamic configuration; Astyanax for interacting with Cassandra; and various other NetflixOSS projects.
- The talks highlighted the motivation for these projects including addressing challenges of scaling for Netflix's large data
This document summarizes Tagomori Satoshi's presentation on handling "not so big data" at the YAPC::Asia 2014 conference. It discusses different types of data processing frameworks for various data sizes, from sub-gigabytes up to petabytes. It provides overviews of MapReduce, Spark, Tez, and stream processing frameworks. It also discusses what Hadoop is and how the Hadoop ecosystem has evolved to include these additional frameworks.
Exactly-once Stream Processing with Kafka StreamsGuozhang Wang
I will present the recent additions to Kafka to achieve exactly-once semantics (0.11.0) within its Streams API for stream processing use cases. This is achieved by leveraging the underlying idempotent and transactional client features. The main focus will be the specific semantics that Kafka distributed transactions enable in Streams and the underlying mechanics to let Streams scale efficiently.

Real time Messages at Scale with Apache Kafka and CouchbaseWill Gardella
Kafka is a scalable, distributed publish subscribe messaging system that's used as a data transmission backbone in many data intensive digital businesses. Couchbase Server is a scalable, flexible document database that's fast, agile, and elastic. Because they both appeal to the same type of customers, Couchbase and Kafka are often used together.
This presentation from a meetup in Mountain View describes Kafka's design and why people use it, Couchbase Server and its uses, and the use cases for both together. Also covered is a description and demo of Couchbase Server writing documents to a Kafka topic and consuming messages from a Kafka topic. using the Couchbase Kafka Connector.

Building Realtim Data Pipelines with Kafka Connect and Spark StreamingGuozhang Wang
Spark Streaming makes it easy to build scalable, robust stream processing applications — but only once you’ve made your data accessible to the framework. Spark Streaming solves the realtime data processing problem, but to build large scale data pipeline we need to combine it with another tool that addresses data integration challenges. The Apache Kafka project recently introduced a new tool, Kafka Connect, to make data import/export to and from Kafka easier.
The document discusses Apache Spot, a new approach to network security that aims to address limitations of traditional SIEM systems. It proposes moving from detection-focused workflows to prioritizing real investigation through anomaly-based detection. Apache Spot leverages open source technologies like Apache Hadoop, Spark, and machine learning to filter billions of events down to thousands for further analysis. It is intended to give partners control over their own data while benefiting from an open data model and community engagement.
Building Realtime Data Pipelines with Kafka Connect and Spark Streaming by Ew...Spark Summit
Kafka Connect allows for building real-time data pipelines with Kafka and Spark Streaming by enabling large-scale streaming data import and export to Kafka. It provides a separation of concerns between connectors that are responsible for importing or exporting data and tasks that run in parallel to perform the work. Kafka Connect supports at least once delivery guarantees through automatic offset checkpointing and recovery. When combined with Spark Streaming, it increases the number of systems Spark Streaming can integrate with and reduces the need for Spark-specific connectors by leveraging Kafka as the streaming data storage layer.
This document discusses Apache Kafka, an open-source distributed event streaming platform. It provides an introduction to Kafka's design and capabilities including:
1) Kafka is a distributed publish-subscribe messaging system that can handle high throughput workloads with low latency.
2) It is designed for real-time data pipelines and activity streaming and can be used for transporting logs, metrics collection, and building real-time applications.
3) Kafka supports distributed, scalable, fault-tolerant storage and processing of streaming data across multiple producers and consumers.
Kafka Streams is a new stream processing library natively integrated with Kafka. It has a very low barrier to entry, easy operationalization, and a natural DSL for writing stream processing applications. As such it is the most convenient yet scalable option to analyze, transform, or otherwise process data that is backed by Kafka. We will provide the audience with an overview of Kafka Streams including its design and API, typical use cases, code examples, and an outlook of its upcoming roadmap. We will also compare Kafka Streams' light-weight library approach with heavier, framework-based tools such as Spark Streaming or Storm, which require you to understand and operate a whole different infrastructure for processing real-time data in Kafka.

Abstract:
"In the past few years Apache Kafka has established itself as the world's most popular real-time, large-scale messaging system. It is used across a wide range of industries by thousands of companies such as Netflix, Cisco, PayPal, Twitter, and many others.
In this session I am introducing the audience to Kafka Streams, which is the latest addition to the Apache Kafka project. Kafka Streams is a stream processing library natively integrated with Kafka. It has a very low barrier to entry, easy operationalization, and a high-level DSL for writing stream processing applications. As such it is the most convenient yet scalable option to process and analyze data that is backed by Kafka. We will provide the audience with an overview of Kafka Streams including its design and API, typical use cases, code examples, and an outlook of its upcoming roadmap. We will also compare Kafka Streams' light-weight library approach with heavier, framework-based tools such as Apache Storm and Spark Streaming, which require you to understand and operate a whole different infrastructure for processing real-time data in Kafka."

Apache Kafka - Scalable Message-Processing and more !Guido Schmutz
Independent of the source of data, the integration of event streams into an Enterprise Architecture gets more and more important in the world of sensors, social media streams and Internet of Things. Events have to be accepted quickly and reliably, they have to be distributed and analysed, often with many consumers or systems interested in all or part of the events. How can me make sure that all these event are accepted and forwarded in an efficient and reliable way? This is where Apache Kafaka comes into play, a distirbuted, highly-scalable messaging broker, build for exchanging huge amount of messages between a source and a target.
This session will start with an introduction into Apache and presents the role of Apache Kafka in a modern data / information architecture and the advantages it brings to the table. Additionally the Kafka ecosystem will be covered as well as the integration of Kafka in the Oracle Stack, with products such as Golden Gate, Service Bus and Oracle Stream Analytics all being able to act as a Kafka consumer or producer.
This document discusses new age distributed messaging using Apache Kafka. It begins with an introduction to Kafka concepts like topics, partitions, producers and consumers.
