We have a use case where we effectively need to have a relational database, but in git. The database doesn't change much, but when it does, references between tables may need to be updated. But we need to easily be able to see diffs between different versions. We're trying an SQLite DB, with exports to CSV as part of CI - the CSV files are human-readable and diff'able.
It's also worth noting that SQLite can ingest CSV files into memory and perform queries on them directly - if the files are not too large, it's possible to bypass the sqlite format entirely.
