--------------------------------------------
Summary: Dedicated merge dispatch threadpool on master
Key: HBASE-25528
URL: https://issues.apache.org/jira/browse/HBASE-25528
Project: HBase
Issue Type: Improvement
Components: master
Affects Versions: 3.0.0-alpha-1, 1.7.0, 2.5.0
Reporter: Bharath Vissapragada
Assignee: Bharath Vissapragada
Over the weekend we ran into an issue of running normalizer on a table with
~400k regions and we noticed the master was bottlenecked on a single threaded
thread-pool that was meant for all master table operations (opcode:
MASTER_TABLE_OPERATIONS). Having a dedicated thread-pool helped us dispatch
merges at a faster rate.
