Ishan Chhabra commented on HBASE-9950:
--------------------------------------
[~stack] not sure yet. Since there is no notion of row level data in hbase
storage, I would have to create some special KVs that are stored for the row,
which sounds very hacky.
[~apurtell] Replication scope is defined at the CF level, so I don't think Ill
be able to use it. I do need to plug in custom replication policy though if
this is not a core feature. There are no observers for replication, are there?

> Key: HBASE-9950
> URL: https://issues.apache.org/jira/browse/HBASE-9950
> Project: HBase
> Issue Type: Bug
> Components: Replication
> Reporter: Ishan Chhabra
> Priority: Minor
>
> We have a replication setup with the same table and column family being
> present in multiple data centers. Currently, all of them have exactly the
> same data, but each cluster doesn't need all the data. Rows need to be
> present in only x out of the total y clusters. This information varies at the
> row level and thus more granular replication cannot be achieved by setting up
> cluster level replication.
> Adding row level replication should solve this.
