Add TimeRange support into Increment to optimize for counters that are
partitioned on time
------------------------------------------------------------------------------------------
Key: HBASE-3162
URL: https://issues.apache.org/jira/browse/HBASE-3162
Project: HBase
Issue Type: Improvement
Components: client, regionserver
Affects Versions: 0.90.0
Reporter: Jonathan Gray
Priority: Minor
In many use cases of increments, a given counter is only incremented during a
specific window of time (ie. the counters are partitioned/sharded by time).
With this kind of schema, you are constantly creating new counters. When a new
counter is "created" (incremented the first time) you will always end up
looking at a block from every file in the region because no previous value will
exist. However, with the new TimeRange optimizations that skip files if they
don't contain values of the TimeRange you're interested in, we could utilize
that information to optimize the Get within the increment.
This would be optional and an addition to the Increment class.
