Change subject: IMPALA-12399: Add filter to skip OPEN_TXN events from HMS ...................................................................... IMPALA-12399: Add filter to skip OPEN_TXN events from HMS 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 metastore 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 hive metastore and catalogd. Catalogd reads events in batches of EVENTS_BATCH_SIZE_PER_RPC, skipping such unnecessary events can help catchup the events faster.
