We've generally tried to avoid adding utils modules since it's a kitchen sink/code smell. If this AtomicCounter is only used in this datastore class, maybe we can just define it here? Or rename feast.utils.generic_utils to feast.atomic or something?

I'm actually glad to hear this :) I wanted to use the patterns of the codebase. I'm going to move it into an innerclass just for the _delete_all_values since it's only used for that logging statement (or we could remove the logging), and it can always be migrated to increasing scope if needed.

Nit is there a doc we can link to in case this changes in the future?

I just went looking and couldn't find an obvious place. If we try to query with more than 500, the server responds:
google.api_core.exceptions.InvalidArgument: 400 cannot write more than 500 entities in a single call
