             Summary: Pluggable policy for smallestReadPoint in HRegion
                 Key: HBASE-6427
                 URL: https://issues.apache.org/jira/browse/HBASE-6427
             Project: HBase
          Issue Type: New Feature
            Reporter: Lars Hofhansl
            Priority: Minor


When implementing higher level stores on top of HBase it is necessary to allow 
dynamic control over how long KVs must be kept around.
Semi-static config options for ColumnFamilies (# of version or TTL) is not 
sufficient.

The simplest way to achieve this is to have a pluggable class to determine the 
smallestReadpoint for Region. That way outside code can control what KVs to 
retain.
