Sergey Shelukhin commented on HBASE-8134:
-----------------------------------------
To improve common case (no weird TS manipulations), we can move earliest put ts
calculation from compactor to policy, to consider all files for it, including
the ones left out. In that case we can determine during file selection what the
drop deletes cutoff is. It is safe, and in common case will allow minor
compaction of oldest files to drop deletes.
