------------------------------------
Summary: Initiator speed-up: only read compaction history once per
loop
Key: HIVE-25442
URL: https://issues.apache.org/jira/browse/HIVE-25442
Project: Hive
Issue Type: Improvement
Reporter: Zoltan Chovan
Assignee: Zoltan Chovan
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.
