Hi all 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 ` 2 In prefect 1 0 if a task returns a dictionary and I specify as above how to locally cache why may be getting that `result pkl` only saves the last element in the dictionry Thanks

Hi I believe you re asking about this <https docs prefect io latest concepts results h=results persisting results>

I was reading that documentation but I am bit confused by the cache keys It seems like they rely in the task input rather than if the resulting file exists or not

Zanie · Answer

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

Marco Barbero Mota · Answer

Are there examples out there

Marco Barbero Mota · Answer

I see and then how should I pass that to the task decorator

For 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
