    Description

      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).
