-----------------------------------------
This can be implemented by WALObserver coprocessor. But do you think we should
keep this feature internal to our install or do you think we should contribute
it back to Apache? If we can put it somewhere in open source (not necessarily
in Apache, is github preferable?), we can also open source our
cluster-replication software.

> 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).
