The exchange is simply a record in memory. It's not especially big, but
it is a resource. Provided you don't run out of memory, there's no other
limiting factor. Of course, if each exchange has several bindings to
several queues and you end up with millions of queues then yes, you will
find that much harder to achieve, it's not impossible though, provided
you have juicy enough hardware.
