Ability for an application to store metadata into the transaction log
---------------------------------------------------------------------

                 Key: HBASE-4477
                 URL: https://issues.apache.org/jira/browse/HBASE-4477
             Project: HBase
          Issue Type: Improvement
            Reporter: dhruba borthakur
            Assignee: dhruba borthakur


mySQL allows an application to store an arbitrary blob along with each transaction in its
transaction logs. This JIRA is to have a similar feature request for HBASE.

The use case is as follows: An application on one data center A stores a blob of data along
with each transaction. A replication software picks up these blobs from the transaction logs
in A and hands it to another instance of the same application running on a remote data center
B. The application in B is responsible for applying this to the remote Hbase cluster (and
also handle conflict resolution if any).
