---------------------------------------
Summary: Cross cluster replication of the base table only should
be sufficient
Key: PHOENIX-5315
URL: https://issues.apache.org/jira/browse/PHOENIX-5315
Project: Phoenix
Issue Type: Improvement
Reporter: Andrew Purtell
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).
