             Summary: Improve performance of move_servers_rsgroup and move_tables_rsgroup by using async region move API
                 Key: HBASE-24025
                 URL: https://issues.apache.org/jira/browse/HBASE-24025
             Project: HBase
          Issue Type: Improvement
          Components: rsgroup
            Reporter: Mohammad Arshad
            Assignee: Mohammad Arshad


Currently move_servers_rsgroup and move_tables_rsgroup commands and APIs are taking lot of time.
In my test environment, to move a server with 100 regions it takes around 137 seconds.
Similarly it takes around same time to move a table with 100 regions to other group.

The time taken in rsgroup meta update is  negligible. Almost all the time is taken in region moment. This is happening because region is moved serially using  getAssignmentManager().move(region) API

API getAssignmentManager().moveAsync(regionplan)  can be used to move the regions in parallel to improve the performance of region group move servers and tables commands and APIs
