Maybe I'm missing something obvious but all I see is the source amalgamation, not the files used to generate the giant source code file. Did they take the SQLite source amalgamation and write their changes directly against that?
Came here to post this. I'm super interested in versioned databases. They provide so many things "you're going to want" (audit log of changes over time, point in time queries, undo/redo) "for free". Dolt is the one I'm most hopeful for.
ooh this is really cool. hopefully it works with something like spatialite. i have a need to store the OpenStreetMap road network at various points in its history and being able to branch and update those branches without each consuming gigabytes more of data would be super useful.
