first of all, great library, easy to understand and fast.

I came across the issue, that I was looking for a status of a task. So far I did not see this feature in the documentation, but you linked a database solution in your [](flask example ).

Is it also possible to track the task status in the broker and/or backend?

Further, is it possible to distinguish between an existing task in the backend and non-existing one?
I would expect some error for a task that does not exist and a status for an existing task.

Hello! I love this library too!

For tracking statuses (success/error) you can follow this instruction:

More info about it you can find here:

So, in basic cases maybe you need:

Hi @dmitry-vakhnenko,

thank you for the hints and tried some of them, especially the results but I am still not happy with my result.

Let me describe you how what I want to achieve:

  1. I sent a Message via an Actor with message = add.send(1, 2) - from there I get back an message_id from the broker
  2. I want to store this message_id e.g. in a MySQL database before it is accessible with message.get_result(backend=backend) --> Here I do not know if any of the Middleware functions are of any help for this use case
  3. If 1 and 2 are in place, I can distinguish between an existing message/task and a non-existing one, by querying the database.
  4. Further I can update the status of the message/task in the database over the time of the process.

@MaxRichter since this is essentially a question, would you mind moving the discussion over to the forum at

To answer your question, though, this is possible via middleware. You can check out the AdminMiddleware in django_dramatiq for an example.
