anishek updated HIVE-20679:
---------------------------
Description:
Certain type of ddl operations might create large messages as part of
DBNoitification, this might lead to the rdbms throwing an error when storing
the message since its size is to large. It will also increase the footprint of
the rdbms space usage.
We should try store compressed messages to allow handling these situations.
Edit: For notification_log table the message column for all supported databases
can store messages from 2GB to 4GB
