---------------------------------------
Assignee: Palash Chauhan
> Create RegionServerCoprocessor to invalidate cache.
> ---------------------------------------------------
>
> Key: PHOENIX-6968
> URL: https://issues.apache.org/jira/browse/PHOENIX-6968
> Project: Phoenix
> Issue Type: Sub-task
> Reporter: Rushabh Shah
> Assignee: Palash Chauhan
> Priority: Major
>
> Whenever we update metadata (like alter table add column, drop table), we
> need to invalidate metadata cache entry (introduced by PHOENIX-6943) on all
> the regionservers which has that cache entry. First step would be to issue an
> invalidate command on all the regionservers irrespective of whether that
> regionserver has the cache entry. We can further optimize by invalidating
> only on RS that has that cache entry.
> We need to have co-processor method something like
> invalidateCache(CacheEntry) and since we maintain this cache at the
> regionserver level, we can add it in
> RegionServerObserver/RegionServerCoprocessor and add this coprocessor to all
> the regionservers.
> Recently [~vjasani] added
> ReplicationSinkEndpoint/ReplicationSinkCompatEndpoint in
> PHOENIX-5521. We can rename that to
> PhoenixRegionObserver/PhoenixRegionServerCoprocessor so that we can
> consolidate all the endpoints in the same class.
