> Key: HBASE-26073
> URL: https://issues.apache.org/jira/browse/HBASE-26073
> Project: HBase
> Issue Type: Improvement
> Components: Normalizer
> Affects Versions: 1.7.0, 2.4.4
> Reporter: Aman Poonia
> Assignee: Aman Poonia
> Priority: Minor
>
> 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.
