> 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.
