Yep, I&#x27;ve used this too in simple flask programs. Pretty simple, and it&#x27;s great when you don&#x27;t really need to do anything beyond simple data storage and retrieval. It&#x27;s upsert functionality is pretty handy—particularly pre-DB support. Not that any of this couldn&#x27;t be done by hand, but why when you don&#x27;t have to?
