Does the api support progress reporting? ("30 % done")
Of course one could build this manually when you're building the worker implementation but I'd love to have it reflected in the api somewhere. Celery also seems to be missing api for that.
Anyone sees a reason why that's missing? I don't think it complicates the api much and seems such an obvious thing for longer-running background tasks.
Though, I imagine you could have strategies to give an approximation of it, for example like keeping track of the past execution time of a given type of task in order to infer the progress of a currently running task of the same type.
No. You just need to know the total number of steps and what step are you currently on.
Does anyone know a task queue library that implement it ? I would be curious to look at it !
I first learned about it from Miguel Grinberg's Flask tutorial: https://blog.miguelgrinberg.com/post/the-flask-mega-tutorial... But the same concept applies to Django.
