The Splitgraph core code on GitHub [0], around which we've built the DDN, is all about managing "data images" which are basically snapshots of PostgreSQL schemata. You can build them with a format similar to Dockerfiles as well as do a "checkout" into a local instance of Splitgraph (which you can connect to with any PG client) -- this enables change tracking and delta compression too. Behind the scenes, we store them as cstore_fdw [2] files which is a columnar storage format that helps with analytical queries.
