Andrew Purtell commented on HBASE-10309:
----------------------------------------
Or you could create your keys based on a modulus of the timestamp? Could work
if you can put an upper bound on the number of records stored within the
retention period, call it N, then key = (timestamp mod N) ...
> Add support to delete empty regions in 0.94.x series

> Fix For: 0.94.16

>
> My use case: I have several tables where keys start with a timestamp. Because
> of this and combined with the fact that I have set a 15 days retention
> period, after a period of time results empty regions.
> I am sure that no write will occur in these region.
> It would be nice to have a tool to delete regions without being necessary to
> stop the cluster.
> The easiest way for me is to have a tool that is able to delete all empty
> regions, but there wouldn't be any problem to specify which region to delete.
> Something like:
> deleteRegion <tableName> <region>
