Oh, it looks like we'll also want to add that condition here too: https://github.com/WordPress/openverse/blob/c0105eb1b89aae9d3548f42ef69be52c5e863609/catalog/dags/providers/provider_api_scripts/inaturalist.py#L331

Apologies for missing that! Using the Variable there as well will prevent the dataset from being redownloaded every time.

@AetherUnbound all suggested code changes have been made. P.S: I am unable to verify the intended behavior on my end due to repeated failures while trying to download the inaturalist_workflow source files(they seem quite large and I have a not-so-reliable internet). I'm hoping there's a way for you to verify and okay this from your end.

@madewithkode thanks for making those changes! I was able to test this locally, and opted to make two other changes:

• Set the default of the parameter to False, since we now have the Variable which can act as a default/fallback
• Change the condition for removing the files to or, so only one of them has to be specified as true in order to ensure deletion

This has the effect making it so that either the parameter or the Variable being set will remove the files, but by default locally, they won't be removed. In production, since we have the Variable set to true, it will always be removed.

I was able to verify this behavior by:

• Run the DAG once (so the file was downloaded) and check that the cleanup tasks were skipped
• Mark the DAG as failed after it is completed (so a follow-up run doesn't skip during the "check previous success" step)
• Run the DAG again and verify that the load_catalog_of_life_names tasks doesn't have to redownload the COL files.

All that to say, this looks good to me and can be taken out of draft when you're ready!

@AetherUnbound All these makes sense. Proceeding to unmark the PR as draft now. Thank you for the extra effort!
