-------------------------------------
Summary: 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
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.
