Subject [jira] [Created] (HBASE-9951) Tags for HLogKey
Date Mon, 11 Nov 2013 22:44:20 GMT
Ishan Chhabra created HBASE-9951:

             Summary: Tags for HLogKey
                 Key: HBASE-9951
                 URL: https://issues.apache.org/jira/browse/HBASE-9951
             Project: HBase
          Issue Type: New Feature
          Components: wal
            Reporter: Ishan Chhabra

Similar to the Cell Interface, adding tags for the HLogKey could be useful for multiple scenarios.

My primary use cases are driven from replication though:
1. To record whether a WALEdit should be forwarded further to other clusters (see [#HBASE-9934])
2. To record which clusters the WALEdit should be forwarded to (for Row level replication)
3. To mark a record for not replicating (these are some special cases in our usage and cannot
be handled using a separate column family)
