-------------------------------------

             Summary: Add regular expression based split policy
                 Key: HBASE-12452
                 URL: https://issues.apache.org/jira/browse/HBASE-12452
             Project: HBase
          Issue Type: Improvement
          Components: regionserver
            Reporter: He Liangliang
            Assignee: He Liangliang
            Priority: Minor


The current DelimitedKeyPrefixRegionSplitPolicy split policy is not flexible enough to describe
the split point prefix in some case. A regex based split policy is proposed, for example:
    ^[^\x00]+\x00[^\x00]+\x00
means the split point will always be truncated to a prefix at the second \0 char. We rely
on this to implement local secondary index with data types.
