What is the order of the callbacks being fired when 2 callbacks share same inputs

Hi,
I have 2 callbacks, 1 with 4 inputs and the other with a single input which is shared with the first callback. I want to know if there is any order for the callbacks being fired which share same inputs.

Thanks

There isn’t any order. If you run with multiple workers, they could even be executed in parallel (one by each each worker)
