A couple of questions:
1. Anyone could point me to what is the functionality in prefect 2.0 that does the same as
@task(LocalResult(dir='path/to/folder/for/storage),target='result.pkl',checkpoint=True)result.pkl✅ 1

You could write a custom cache key function that checks for the presence of a file

05/16/2023, 11:46 PMFor anyone else interested, I ended up writing my own custom cache key function. I will be creating a public repo on my GitHub for anyone else that wants this functionality. Would be great if prefect could implement it in the package itself.
