I'm glad to hear that the current normalizer configuration and features are sufficient for your needs.

> 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 regionservers in creating plans for normalizer.
