Well, they are just a mechanism to push jobs between different components where you treat Redis as a message queue. In Redis you can implement one using Lists, Sorted Sets, Stream or Pub/Sub; though they are commonly implemented through the first two. Though if you end up using first two, to guarantee at least once semantics you need to take care of acknowledgement in a not so pleasant way.

You can replace Redis with pretty much any message queue though like RabbitMQ which has a better consumption story. The main advantage of using any one of these would be the throughout you can achieve and it decouples your database at that point which a lot of people prefer.
