Tianying Chang commented on HBASE-13639:
----------------------------------------

Nice idea! I am wondering if the source table has constant write into it, what will be the outcome? Or I guess  this feature is meant for source table that is not being updated? Thanks

> Given HBase tables in remote clusters with similar but not identical data, efficiently update a target table such that the data in question is identical to a source table.  Efficiency in this context means using far less network traffic than would be required to ship all the data from one cluster to the other.  Takes inspiration from rsync.
