@shenjiayu17 & @marchpure @QiangCai : **Have you analyzed which exact change is responsible for performance improvement?** I don't think it is because of listFiles changes as it will make difference only if stale files are present. Probably writing as a new segment. But still, I don't get why this much difference, I think you have enabled horizontal compaction, now there is no horizontal compaction. You cannot call it as improvement as the query will slow down due to many segments and actual compaction need to run. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
