    Description

      Consider an usecase where row keys has an increasing value(time-series data for example) and data retention is set to a concrete value(60 days for example).
      After a period of time, longer than retention, empty regions will appear. This will cause high memory use on region servers.
      In my opinion, regions merge could be part of major compaction or another tool should be provided. From my understading, it is possible to merge 2 empty regions without make table offline, but it's not possible to merge one empty region with a non-empty region without close/unassing this regions.
