Zhihong Yu commented on HBASE-4991:
-----------------------------------
@Todd:
In HMasterInterface, there is already API exposing the concept of regions:
{code}
public void move(final byte [] encodedRegionName, final byte []
destServerName)
throws UnknownRegionException;
{code}
In this regard, the new API doesn't expose newer concept:
{code}
public void deleteRegion(List<byte[]> encodedRegionNameList)
{code}
The above is, I think, equivalent to deleteRange() you proposed. Maybe the
above is better in that we don't need to validate that startKey is the first
key of some region, etc.
I think splitting the underlying region(s) of specified table in case startKey
is not the first key is outside the scope of this JIRA.
For use case, we have an internal team which requests this feature. They can
manage to age the data in selected regions such that they can drop whole
region(s) quickly.
