Redis pubsub and horizontal scaling?

Question

Redis

pubsub is used to exchange data between different services. When creating multiple workers, they will both receive data and both will process it. What methods are there so that only one of the workers works for one message.
PS Probably there are some layers, the so-called message brokers.

Answer 1

the PUB-SUB pattern is not suitable for your task, you need PUSH-PULL (in ZeroMQ terms, for example zguide.zeromq.org/page:all ).
