Скачать или смотреть Kafka Streams and KSQLDB by Daniel Hinojosa

Kafka is more than just a messaging queue with storage. It goes beyond that, and with technology from Confluent open source, it has become a full-fledged data ETL and data streaming ecosystem. When we utter the words, Kafka, it is no longer just one component but can be an entire data pipeline ecosystem to transform and enrich data from source to sink. It offers different ways to handle that data as well. In this presentation, we define:

Streaming Concepts
Using functional programming to manipulate your data
Co-partitioning
Aggregations

We then discuss KSQLDB. A SQL layer built upon Kafka Streams that provides a simple query
language to perform streaming operations:

Persistent Queries
Non-Persistent Queries
Fault-Tolerance
