Redis, ZMQ, etc. Is it possible to implement something like pub/sub and queue at the same time?

Question

Python

Good day.
There was a problem at implementation of EventBus'a. It is necessary to implement receiving messages in two ways: for all clients and for the first one that grabs. That is, send messages as in pub / sub or as in queue, depending on the type of message. I write in Python. I planned to use something light as a broker, such as Redis or ZeroMQ. (Maybe you can suggest other options.)
Is there any way to implement this feature?

Answer 1

Look - there are 2 main mechanics - push-based and pull-based. pub/sub is just one of the de facto principles of queues.
what you want to implement is the difference between exchange and queue in RabbitMQ. I wouldn’t recommend ZeroMQ to anyone at all, and Redis isn’t really about queues either - they just know a little about them
