Move pending tasks to a different task queue

[Vikas_Unnava]

We have a use case where we have a need for prioritized activity execution. I understand that temporal doesnt support priority in the task queues. So, we are trying to use multiple task queues one per priority.

However, once in a while we will need to reprioritize pending activities(ones waiting in the task queue). My original idea was to cancel the activities and reschedule them on a different task queue when I receive the signal in the workflow, but this approach also cancels running activities which we dont want. We only want to move the activities that havent been picked up by a worker yet.

Really appreciate the help and hoping for a workaround.

A workaround is for this activity to send a signal to a workflow at the beginning of the execution.

Interesting! Very helpful, thanks!

Activities can ignore the cancellation requests. If they don’t heartbeat, they will not receive the cancellation request anyway.
