>
> I would like to add new compaction tools based on [~churromorales]'s tool at
> HBASE-19528.
> We internally have tools that pick and compact regions based on multiple
> criteria. Since Rahul already has a version in community, we would like to
> build on top of it instead of pushing yet another tool.
> With this jira, I would like to add a tool which looks at regions beyond TTL
> and compacts them in a rsgroup. We have time series data and those regions
> will become dead after a while, so we compact those regions to save disk
> space. We also merge those empty regions to reduce load, but that tool comes
> later.
> Will prep a patch for 2.x once 1.5 gets in.
