----------------------------------
Labels: pull-request-available (was: )
> Initiator: Optimise when tables/partitions are not eligible for compaction
> --------------------------------------------------------------------------
>
> Key: HIVE-24943
> URL: https://issues.apache.org/jira/browse/HIVE-24943
> Project: Hive
> Issue Type: Improvement
> Reporter: Rajesh Balamohan
> Priority: Major
> Labels: pull-request-available
> Time Spent: 10m
> Remaining Estimate: 0h
>
> When the entire database isn't qualified for compaction due to replication,
> initiator could potentially skip the entire table/partition checks to save
> HMS resources. Currently it runs in tight loop for each table/partition for
> the database which isn't eligible for compaction.
> E.g Note that for "delete_orc_10" database repl parameters are enabled. So
> until "ReplUtils.isFirstIncPending(database.getParameters());", it ends up
> considering that entire database as "not chosen for compaction".
