-------------------------------------
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.
