I was running a prefect flow but facing a run out of memory issue, how can I clear up and free the space. I saw a 17G .prefect file in the root directory, can I remove it?

You can delete those files if you don’t need them. They are checkpoints from the flow runs. You can also turn off checkpoints with

@task(checkpoint=False)
def ...

Thank you for your reply!! Can I clean the checkpoints for a specific flow since we have several flows ran.

These checkpoints are mainly for restarting a flow run from failure. Instead of re-running the previous tasks, it will pull the checkpoint. So you can delete most of them safely

Thanks!!! So for accessing the checkpoints - I cd into .prefect/flows/name_of_my_flow , I see multiple files in there - is this the correct place to delte the checkpoints? and how do I know which one is the latest ?

yes exactly. can you sort it by time?

Okay, can i remove the entire folder or remove all the checkpoints inside.

All might be aggressive but as long as you dont have future flows that rely on these, yeah it should be fine

Thank you very much! Space error fixed!
