Victoria Xia created KAFKA-14491: ------------------------------------ Summary: Introduce Versioned Key-Value Stores to Kafka Streams Key: KAFKA-14491 URL: https://issues.apache.org/jira/browse/KAFKA-14491 Project: Kafka Issue Type: Improvement Reporter: Victoria Xia Assignee: Victoria Xia
The key-value state stores used by Kafka Streams today maintain only the latest value associated with each key. In order to support applications which require access to older record versions, Kafka Streams should have versioned state stores. Versioned state stores are similar to key-value stores except they can store multiple record versions for a single key. An example use case for versioned key-value stores is in providing proper temporal join semantics for stream-tables joins with regards to out-of-order data.
