> Event-processor is designed to get rid of manual RT/IM (RefreshTable / InvalidateMetadata) commands that sync up with external HMS modifications. However, event processing could be delayed. Queries might still see stale metadata if the event-processor is lagging behind. We should provide a mechanism to let query planning wait until the metadata is synced up. Users can turn it on for sensitive queries that depend on external modifications.
