VenuReddy2103 opened a new pull request, #58:
URL: https://github.com/apache/impala/pull/58
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.
