Sorry if this has been asked/answered before. One thing I really miss from other orchestrators is a simple way to specify how concurrency for a flow should behave. In Airflow I believe this is controlled with using a

LatestOnlyOperator

or using

depends_on_past

. In Oozie (I know, not my favorite orchestrator), this could be achieved by setting a

concurrency

to

1

and

execution

to

FIFO

or

ONLYLAST

. Are there any plans in Orion to provide similar functionality so users don’t have to implement custom solutions to this common pattern?

Yes absolutely there is a plan to make this first class in Orion. It still can be somewhat achieved in current Prefect with FlowRun Concurrency
