> Hivemetastore Performance: Compaction Initiator Thread overwhelmed if there
> are too many Table/partitions are eligible for compaction
> --------------------------------------------------------------------------------------------------------------------------------------
>
> Key: HIVE-22081
> URL: https://issues.apache.org/jira/browse/HIVE-22081
> Project: Hive
> Issue Type: Improvement
> Components: Transactions
> Affects Versions: 3.1.1
> Reporter: Rajkumar Singh
> Assignee: Rajkumar Singh
> Priority: Major
> Attachments: HIVE-21917.01.patch, HIVE-21917.02.patch,
> HIVE-21917.03.patch, HIVE-22081.04.patch, HIVE-22081.patch
>
>
> if Automatic Compaction is turned on, Initiator thread check for potential
> table/partitions which are eligible for compactions and run some checks in
> for loop before requesting compaction for eligibles. Though initiator thread
> is configured to run at interval 5 min default, in case of many objects it
> keeps on running as these checks are IO intensive and hog cpu.
> In the proposed changes, I am planning to do
> 1. passing less object to for loop by filtering out the objects based on the
> condition which we are checking within the loop.
> 2. Doing Async call using future to determine compaction type(this is where
> we do FileSystem calls)
