I noticed you’re simply scaling redis without any special cluster configuration. Is that not required? I know that the workers will round-robin drain the instances but would their ack messages not possibly end up going to the wrong instances sometimes? Or do they maintain the connecting and go back to the one where they received their work item from? I was under the impression the redis would need to sync state in order for workers to be able to connect to any node at random.

One clap, two clap, three clap, forty?

By clapping more or less, you can signal to us which stories really stand out.
