@shahrs87 Refreshing live region servers in CQSI.init creates issues for the
Permission related ITs. I have added a feature flag check in CQSI.init for now.
We can look into those failing ITs as part of another sub-task to turn the
feature on.
> Create a new RPC to validate last ddl timestamp for read requests.

> 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.
