--------------------------------------
Summary: Session Window store should set topic policy
`compact,cleanup`
Key: KAFKA-7101
URL: https://issues.apache.org/jira/browse/KAFKA-7101
Project: Kafka
Issue Type: Improvement
Components: streams
Affects Versions: 0.10.2.2, 2.0.0, 0.11.0.3, 1.0.2, 1.1.1
Reporter: Matthias J. Sax
Assignee: Guozhang Wang
With
[KIP-71|https://cwiki.apache.org/confluence/display/KAFKA/KIP-71%3A+Enable+log+compaction+and+deletion+to+co-exist]
(0.10.1.0) topic config `compact,delete` was introduce to apply to windowed
store changelog topics in Kafka Streams. Later (0.10.2.0), session windows got
added in
[KIP-94|https://cwiki.apache.org/confluence/display/KAFKA/KIP-94+Session+Windows].
However, session windows do not use `compact,delete` at the moment. This
result is the same issue window stores face before KIP-71. Thus, we should
enable `compact,delete` for session window changelog topics, too.
