himanshug commented on issue #8489: Stateful auto compaction URL: https://github.com/apache/incubator-druid/issues/8489#issuecomment-535262115 just trying to wrap my head around compaction, I have few questions, it has evolved alot :) 1. Does coordinator auto compaction always do "minor compaction" ( described in https://github.com/apache/incubator-druid/issues/7491 )? 2. Same `CompactionTask` is used for both "minor" as well as "major" compaction. It is major compaction when either of "interval" or "segmentGranularity" fields are explicitly provided ? > If it exists, the coordinator compares the compactionPartitionsSpec that partitionsSpec in auto compaction configuration. The segment will be a compaction candidate if it has a different partitionsSpec. or else auto/minor compaction would produce exactly same result because it doesn't change segmentGranularity... right ?
