> 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.
