I don't think so. For one, he wants it to run in the browser, and SQLite doesn't run in the browser. In his "embedded" section, he makes it pretty clear that he doesn't want to build on SQLite: > SQLite is a great example of that: it is a very powerful relational database that runs almost anywhere. What I miss from it that SQLite doesn’t provide is the ability to run it on the browser > Mentat was an interesting project, but its reliance on SQLite makes it inherit most of the downsides (and benefits too) of SQLite itself. Also, I'm sceptical you could make SQLite efficient for an immutable DB, IF you want to support full SQL. A DB like Datomic has to do some pretty crazy stuff to be remotely efficient, and it doesn't even try to support full SQL - a great read on Datomic internals: https://tonsky.me/blog/unofficial-guide-to-datomic-internals https://tonsky.me/blog/unofficial-guide-to-datomic-internals Mentat, the DB he links to, is much less ambitious than this proposal, and had a couple years of work by a number of devs before eventually being shuttered/abandoned. It's about 35K lines of Rust, despite being built on top of SQLite, isn't remotely done, doesn't run in the browser, etc. Even if you did build this proposed DB on top of another DB, to make it efficient, and have all of the features discussed, I strongly suspect that it would be an absolutely massive amount of work.
