Order of task execution #871

Open dikdom opened 2 months ago

dikdom commented 2 months ago

Hello, is there any guarantee of the task execution order depending on the enqueue order? I know this sounds silly as this is a queue but unfortunately I have some contradicting experience. Shall I continue investigating my setup or there is no guarantee of the order of the task executions? Thanks!

Well there are ways to achieve something similar. Forcing lower concurrency, checking previous task status in task handlers. But there are no guarantees in any case.

That is sad, I mean this is meant to be a queue. In theory when there is only one process that executes the tasks, then the order of the executions should be the same order as they were inserted in the queue. Am I missing here something?
