> Notification events like OPEN_TXN are ignored on catalogd {{{}MetastoreEventsProcessor{}}}. So, we can pass eventTypeSkipList with OPEN_TXN in NotificationEventRequest while invoking get_next_notification() to avoid reading such notification messages from HMS and then ignoring on catalogd. OPEN_TXN event being more frequent(received even upon describe table operation from beeline), we can significantly reduce unwanted processing on both HMS and catalogd. Catalogd reads events in batches of EVENTS_BATCH_SIZE_PER_RPC, skipping such unnecessary events can help catchup the events faster.
