-----------------------------------
Resolution: Fixed
> Create PhoenixRegionServerEndpoint#invalidateCache method 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: Rushabh Shah
> 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.
> In PHOENIX-6988 we created PhoenixRegionServerEndpoint implementing
> RegionServerCoprocessor. We can create a new method in this co-proc something
> like invalidateCache(CacheEntry) to invalidate cache for a given
> table/view/index.
