> 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
