> Key: PHOENIX-5315
> URL: https://issues.apache.org/jira/browse/PHOENIX-5315
> Project: Phoenix
> Issue Type: Improvement
> Reporter: Andrew Purtell
> Priority: Major
>
> When replicating Phoenix tables using the HBase cross cluster replication
> facility, it should be sufficient (and must, for correctness and avoidance of
> race conditions and inconsistencies) to replicate the base table only. On the
> sink cluster the replication client's application of mutations from the
> replication stream to the local base table should trigger all necessary index
> update operations. To the extent that won't happen now due to implementation
> details, those details should be reworked.
> This also has important efficiency benefits: no matter how many indexes are
> defined for a base table, only the base table updates need be replicated
> (presuming Phoenix schema is synchronized over all sites by some other
> external means).
