Denys Kuzmenko updated HIVE-25631:
----------------------------------
Description:
In checkFailedCompactions (which is called for every partition in the list of
potentials to compact) we select from metadata table COMPLETED_COMPACTIONS.
But the Initiator main loop already has a ShowCompactResponse. We can use that
instead.
For cases where metadata is huge, this will help speed up the Initiator.
> Initiator speed-up: only read compaction history once per loop
