One of the reasons to use a message broker is to mediate between
publishers and consumers that work at different rates. If you set the
maximum length of the queue to a small number then messages will be
dropped instead of queued when consumers are too slow. Only consider
this option if you can afford to lose messages.

It shouldn't be necessary to introduce another buffer, because that is
what queues do. If you need more buffering then perhaps your broker
needs more memory or faster disks.

These settings make it more likely for the broker to crash by running
out of memory or disk space.
