Hello again, I am running Core/Server at 0.11.5 and have checkpointing set to False in my backend.toml file. Still when the flows run, they create a lot of data in the results-folder which is also not removed automatically. Where else do I have to turn off something to not have this files created, or at least removed afterwards. I suspect that this behaviour is also the reason, why my DaskWorker holds on to a lot of memory after a flow run and then breaks at one point as it does not free up memory at all.

Hi @Matthias - do you have result handlers attached to tasks individually?

something like

@task(result=...)

? no, i do not have that

Ah my apologies - you'll need to pass

checkpoint=False

to each task you want to disable results for.

Oh, okay, did not know. I think the docs are a little bit unclear on this

Matthias is right, the docs actually specify the opposite, that you have to set checkpointing for any results to work https://docs.prefect.io/core/advanced_tutorials/using-results.html

Hm I think the docs could be a little clearer here but if I read correctly it seems that's only true when using just Core, not Server/Cloud:

For Prefect Core server or Prefect Cloud users:

• Checkpointing will automatically be turned on; you can disable it by passing 

checkpoint=False

 to each task you want to turn it off for

Yes, of course. He said he’s running core :)
