> Certain use cases may copy or replicate a subset of a table to a different
> table or cluster. For example, application topologies may map data for
> specific tenants to different peer clusters.
> It would be useful to have a Phoenix VerifyReplication tool that accepts an
> SQL query, a target table, and an optional target cluster. The tool would
> compare data returned by the query on the different tables and update various
> result counters (similar to HBase's VerifyReplication).
