> Key: HBASE-12950
> URL: https://issues.apache.org/jira/browse/HBASE-12950
> Project: HBase
> Issue Type: New Feature
> Components: Region Assignment, regionserver, shell
> Affects Versions: 2.0.0
> Reporter: Esteban Gutierrez
> Priority: Major
>
> We have seen many times during the last few years that when key prefixes are
> time based and the access pattern only consists of writes to recent KVs we
> can end up with tens of thousands of regions and some of those regions will
> not be longer used. Even if users use TTLs and data is eventually deleted we
> still have the old regions around and only performing an online merge can
> help to reduce the excess of regions. Extending the truncate command to
> handle also region ranges can help user that experience this issue to trim
> the old regions if required.
