----------------------------------------------
Summary: Reuse window store for stream-stream self-join
Key: KAFKA-18196
URL: https://issues.apache.org/jira/browse/KAFKA-18196
Project: Kafka
Issue Type: Improvement
Components: streams
Reporter: A. Sophie Blee-Goldman
We can optimize the stream-stream self-join by using only a single copy of the
state store. Right now this operator gets compiled down into two separate
window stores for each side, even though both sides are identical.
See https://github.com/apache/kafka/pull/18111#discussion_r1876844961
