Thanks, I hadn't. Looking into it, I think Toon is asking the question:
Should the DBMS expose the raw storage operations (insert, update, delete) for the application to take the burden of correctness for their physical composition into logical functionality? Or should the DBMS export that logical functionality?
With TigerBeetle, we didn't want people to have to keep cobbling together their transaction processing system, to take that burden of correctness, but to solve this in open source, once and for all, for everyone to build around.
