Hi, great post, thanks for sharing! One question though. Isn't the filesystem broker unsupported? It's in Kombu but not in the Celery docs, which I think means it has code but no maintainer and no official support.
I see it like this: Kombu officially supports the filesystem, has unit tests for the filesystem transport and even recent commits. As Kombu is Celery's underlying messaging library, I think any transport option supported by Kombu is supported by Celery (and the Celery docs are a bit patchy anyway).
Bjoern Stiel Nice. I went looking for a blog post to see how to set it up because the one time I tried I had issues configuring it. Lo and behold, I found yours!
