>
> 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.
