Is there a way to time-limit an op? Say of an API call takes more than 10 min, I know the connection is hung and want it to terminate and trigger a retry

nothing at the dagster level you can make an

op

async

and we will drive the event loop for you, so you can use

asyncio

primitives for timeouts https://docs.python.org/3/library/asyncio-task.html#timeouts
