Thiruvel Thirumoolan updated HBASE-21883:
-----------------------------------------
Release Note:
MajorCompactorTTL Tool allows to compact all regions in a table that have been
TTLed out. This saves space on DFS and is useful for tables which are similar
to time series data. This is typically scheduled to run frequently (say via
cron) to cleanup old data on an ongoing basis.
RSGroupMajorCompactionTTL tool is similar to MajorCompactorTTL but runs at a
region server group level. If multiple tables in an rsgroup are similar to
time-series data, then it runs a single command to clean them up. As more
tables are added/removed from rsgroup, it's easy to have a single command to
take care of all of them.

> 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.
