Anoop Sam John commented on HBASE-17157:
----------------------------------------
+1
Ya if the MOB file size is above this, we exclude those files from compaction.
128 MB is flush size but we allow this to grow 4x before doing a forced/blocked
flush. So in all chance the flushed file's size can grow beyond 192. Also pls
note that for flushing we now consider only cell data size now (not cell java
object overhead and overhead because of addition to CSLM in memstore)
> Increase the default mergeable threshold for mob compaction
