If you hang multiple consumers off a single queue, then that queue's
state is shared and those consumers share the messages out between
them "round robin" style. This is good for the 'master worker'
pattern for example. Now, you can also have multiple queues doing a
master/worker type application. For example you could have four
queues, one for 'large' tasks (messages), one for 'medium', one for
'small', and one more queue that gets a copy of all messages for
logging and management. Each of those queues could be private to one
consumer, or it could be shared among a 'pool' of consumers (eg worker
threads).

In the above 'large'. 'medium', 'small' tasks example, you can load
balance work by size by allocating different numbers of consumers to
each queue. So, if you want to filter your flows in the broker, use
many queues. Using just one queue forces you to manage any filtering
in your thread pool.
