For some usages, i.e., join windows in Kafka Streams, it is desirable to have logs that are both compacted and deleted. In these types of applications you may have windows of time with many versions of key, during the window you only want to retain the latest version of the key, however once the window has expired you would like to have the segments for the window deleted. Kafka doesn’t currently support these semantics as compaction and deletion are exclusive.
