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).
