-----------------------------------
Summary: Avoid merging regions if tables has not reached the state
where numbers of regions are not split because of number of regions
Key: HBASE-26073
URL: https://issues.apache.org/jira/browse/HBASE-26073
Project: HBase
Issue Type: Improvement
Components: Normalizer
Affects Versions: 2.4.4, 1.7.0
Reporter: Aman Poonia
Assignee: Aman Poonia
we have a table on a cluster with 100 regions with default split policy
(SteppingSplitPolicy). This is a small table and will not get loaded with too
much data. Now if region size of table is smaller than the normalizer target
region size than there are chances that normalizer will consider the regions
for merges. But since the number of regions are small split policy will trigger
split on next flush. This is a continuous loop and our cluster will be busy in
these two actions.
We plan to consider number of regions and number of regions in creating plans
for normalizer.
