Is there a way to force a specific mapped task to run in sequence even though the flow is using a local dask executor? I have a flow with a bunch of mapped tasks that I want to run in parallel but one mapped task that i'd like run in sequence.

• for sequential processing, you need LocalExecutor which is the default • for parallel processing, you need LocalDaskExecutor or DaskExecutor • to combine both in a single flow, you can leverage a flow-of-flows with one child flow running sequential and another parallel task runs

If you need it sequential, you might look into task looping as well

Thank you both. Task looping seems like the best approach for this use case.
