> When we run a SHOW DATABASES or SHOW TABLES command on the Hive side, the bindings we create or this check is not with a cache of privileges. This makes the authorization checks slow as for every database/table authorization, request is sent to the Sentry server which pulls privileges from the database. Having a cache will fix this problem
