Now just calculating progress and task info every iteration of the loop instead of checking new data flags. It looks like there may be a race condition of some sort causing inaccurate worker numbers. I might consider thread locks if they work with Redis' pubsub run_in_thread.
Alright, this is kind of funny. Turns out I've been reinventing the wheel this whole time. Celery's GroupResult contains AsyncResult instances with all the data we need to get active worker count, task completion and task encoding progress (with a custom task state definition). So: - dropped Redis database polling - dropped Redis PubSub - use unique worker IDs instead of sequential prefix to easily start additional workers at any time
