Subject [jira] [Commented] (PHOENIX-3817) VerifyReplication using SQL
Date Tue, 15 Aug 2017 16:31:00 GMT

Alex Araujo commented on PHOENIX-3817:
--------------------------------------

[~jamestaylor] now that PHOENIX-153 is in, it would be nice to get this committed. We can
then add support for TABLESAMPLE verification queries.

> 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).
