Rushabh Shah resolved PHOENIX-7025.
-----------------------------------
Resolution: Fixed
> Create a new RPC to validate last ddl timestamp for read requests.
> ------------------------------------------------------------------

> Key: PHOENIX-7025
> URL: https://issues.apache.org/jira/browse/PHOENIX-7025
> Project: Phoenix
> Issue Type: Sub-task
> Reporter: Rushabh Shah
> Assignee: Palash Chauhan
> Priority: Major
>
> Introduce a new RPC request from phoenix client to any region server via
> PhoenixRegionServerEndpoint#validateLastDDLTimestamp. Since the last ddl
> timestamp cache is maintained by all the regionservers, you can choose any
> regionserver randomly. In future, we can make this rpc more resilient by
> sending this rpc to multiple regionservers simultaneously.
> If phoenix client throws StaleMetadataCacheException then invalidate the
> cache on the client side and retry executeQuery method while fetching the
> updated metadata from SYSCAT regionserver.
