RabbitMQ is good for inter-app communication but it's not really a database.

You can use one queue or one queue per user but in the end there has to be an app (or multiple apps) that consumes those messages and stores them somewhere.

Activity collection is certainly a very common use case, see [1] and [2] [3].

As a general advice, you can start with 1 queue and once that queue gets congested, move to
multiple queues (e.g. using consistent hashing exchange) and more consumer apps.
