> Project: Hive
> Issue Type: Improvement
> Components: Standalone Metastore

> Labels: compaction, pull-request-available
> Time Spent: 50m
> Remaining Estimate: 0h

> Currently the TxnHandler uses 2 connection pools to communicate with the HMS:
> the default one and one for mutexing. If compaction is configured incorrectly
> (e.g. too many Initiators are running on the same db) then compaction can use
> up all the connections in the default connection pool and all user queries
> can get stuck.
> We should have a separate connection pool (configurable size) just for
> compaction-related activities.
