There is and 10,000 msg/s is probably beyond what a single queue can handle
on the kind of hardware you get from Heroku
add-ons.

Consistent hashing exchange does what you want but it is not built-in. So
to use it, you will likely have to host
RabbitMQ on your own:

https://github.com/rabbitmq/rabbitmq-consistent-hash-exchange

That said, with message volumes of that magnitude I suspect that
self-hosting will be necessary for other reasons anyway.
