Hi , how can i get unique id for every task that is run in parallel ? if i have task A and i run it with : runs = A.map(listOfInputs, unmapped(input2)) when i print this in A:

task_id = prefect.context.get("task_id", "")

i have the same task_id for every task A run …..

Try:

prefect.context.get("task_run_id", "")

thanks, that is working, get the unique id, the question is why task_id is generated as A_1 for all mapped runs. i wish that each task_id for the same task runs would have a running id, meaning A_1, A-2 , etc.

You can influence task name, but not task id - task id refers to the mapped task, which then spins up many child task runs, but the task itself stays the same I think this is what you are looking for: https://docs.prefect.io/core/idioms/task-run-names.html#naming-task-runs-based-on-inputs

that is great ! thanks for the prompt response !
