If tasks are mapped in the complex way like <https://docs.prefect.io/core/concepts/mapping.html#complex-mapped-pipelines>, does something else need to be done to get them to cache?

I think in general, when you use mapping, you need to <https://docs.prefect.io/core/concepts/templating.html#where-can-i-use-templating|template> the location of the result so that each mapped task gets a separate file. Or you are you talking about `cache_for` and `cache_validator`?

Also the `apply_map` is just a function that adds tasks to your Flow so it should be those tasks that have checkpointing

I was talking about the `cache_for`, sounds like templating is the way to go.

I think templating should help you split out the files yep
