I thought the point of Turso was to offer better concurrency than SQLite currently does. A la https://turso.tech/blog/beyond-the-single-writer-limitation-... and https://penberg.org/papers/penberg-edgesys24.pdf
Would be great if one of the Turso developers can clarify :)
Honestly, if you care about that level of concurrency, it begs the question of why are you using an in process database in the first place?
