Sounds like you know ML then. Anything non-trivial on a spreadsheet is usually best ported to a DB, that's a pretty good rule of thumb. I don't understand about your configs being in json, nor why that makes it more suitable for mongo. If you need to store semistructured blobs of data, relational DBs can do that fine (in BLOB fields), but IIRC postgres supports json, including indexing into individual json subfields. <http://www.postgresqltutorial.com/postgresql-json/> http://www.postgresqltutorial.com/postgresql-json/> but to repeat, I've never used postgres so speak to someone else first who has. If you can do ML as it seems you are, install postgres and just get started on this tutorial stuff here - best of luck!
