  • :spiral_calendar: When: 1 March 2022
  • :speaking_head: Speaker(s): Neil Buesing
  • :notebook_with_decorative_cover: Talk(s): Being Persistent: A Look Into Kafka Streams State Stores

Kafka Streams provides stateful processing to Apache Kafka®. To achieve this, it needs to preserve state. It achieves this by leveraging state-stores. We will explore these state-stores and see how the Kafka Streams DSL uses them for windowed and non-windowed state.

This presentation will provide content useful for those new to Kafka Streams or already using it for application development.


  • Showcasing an application leveraging windowed and non-windowed state stores.
  • See how windowed state-stores handles keys and the partitioning of those keys.
  • See how Kafka Streams uses multiple state-stores so windowed data can be discarded easily when it is no longer needed.
  • Monitoring your state stores.
