The way to limit the folder growing is to consume and acknowledge
messages from the broker. Rabbit will only write messages to disk which
have not been consumed and when necessary - either the messages are
being published persistent (delivery_mode = 2) or the broker is under
memory pressure and is thus writing to disk to free up memory.
If you stop the queues from growing (either by not publishing messages,
or by consuming and acknowledging messages from the queues) then Rabbit
will have no reason to write messages to disk.
