-----------------------------------
Summary: Add a cost function to move the daughter regions of a
recent split to different region servers
Key: HBASE-25222
URL: https://issues.apache.org/jira/browse/HBASE-25222
Project: HBase
Issue Type: Improvement
Reporter: Sandeep Pal
Assignee: Sandeep Pal
In HBase, hotspot regions are easily formed whenever there is skew and there is
high write volume. Few regions grow really fast which also becomes the
bottleneck on the few region servers.
It would be beneficial to add a cost function to move the regions after the
split to differetn region servers. In this way the writes to hot key range will
be distributed to multiple region servers.
