06/13/2022, 11:28 AMHi all, is there a way I can specify a task to run only once within a flow? I have noticed some of my tasks run concurrently, this is an issue when I am writing to a table

you can set a limit of 1 to only allow one active flow run of a given flow
(or one active task run with a given tag)
and to ensure your tasks run sequentially, you can use SequentialTaskRunner in Prefect 2.0 and LocalExecutor in Prefect 1.0

06/13/2022, 11:34 AMThank you Anna, is there documentation I could use to look this up? https://prefect-community.slack.com/archives/CL09KU1K7/p1655119965466709?thread_ts=1655119693.324589&cid=CL09KU1K7

1.0 https://docs.prefect.io/
2.0 https://orion-docs.prefect.io/
and search for concurrency limits
