“Stream processing has never been a more essential programming paradigm. Mastering Kafka Streams and ksqlDB illuminates the path to succeeding at it.” -Jay Kreps, Co-creator of Apache Kafka and Co-founder and CEO of Confluent
We live in a world of exponential data growth, and businesses are increasingly built around events - the real-time data in a company. But what is the right infrastructure for harnessing this real-time data? What are the best technologies to integrate databases and process, enrich, and transform data in real-time?
Enter Kafka Streams and ksqlDB.
About Kafka Streams:
Kafka Streams is a stream processing library built for Apache Kafka. It allows companies to process data in real-time, enabling resilient stream processing operations like filters, joins, maps, aggregations, and other transformations. It also gives companies the option to perform stateful stream processing by defining the underlying topology.
About ksqlDB:
ksqlDB is a new kind of database purpose-built for stream processing apps. It gives you one mental model, in SQL, for doing everything you need with data in motion: data acquisition, processing, and querying. ksqlDB has just one dependency: Apache Kafka®.
While working with unbounded and fast-moving data streams has historically been difficult, Kafka Streams and ksqlDB make building stream processing applications easy and fun.
In this practical guide, Mitch Seymoure shows software engineers how to use these tools to build highly scalable stream processing applications for moving, enriching, and transforming large amounts of data in real-time.
Learn important stream processing concepts, use cases, and several interesting business problems. You’ll learn the strengths of both Kafka Streams and ksqlDB to help you choose the best tool for each unique stream processing project. Non-Java developers will find the ksqlDB path to be an especially gentle introduction to stream processing.
