CRDT

Surprised someone has not mentioned CRDT yet .

Corrosion has it .

Nats Jetstream will have it soon . But will not be fully open as nats is changing to BCL license sadly .

Nats SQLite sync works too. https://github.com/wongfei2009/harmonylite

I have been using corrosion to replace nats in some cases . The CRDT is far simpler than running a NATS cluster .

It would be amazingly useful to incorporate it somehow.. how is the tricky bit

Building something like that on top of these bindings/driver is viable, but I'm not sure it belongs in the repo.

As for corrosion, it seems to be based on cr-sqlite which is an SQLite extension made in Rust.

If you want to use something like that here, you either re-write all of it in Go using SQLite APIs (I did just that for many smaller extensions), or you try to build the Rust version to Wasm, same as sqlite-vec did.

In that case the author of the sqlite-vec did it, but there's nothing stopping a user of cr-sqlite doing the same. I would encourage you to give it a try!

Your assertions I agree with .

However corrosion can currently compile to WASM .

https://github.com/search?q=repo%3Asuperfly%2Fcorrosion%20WASM&type=code

so it’s going to be not too hard to integrate as an extension ?

Saved by WASM again ?

I honestly don't know. It might mean the cr-sqlite extension compiles to Wasm? I haven't worked with Rust, so I wouldn't know.

But Corrosion seems much more complicated, regardless if it compiles to Wasm.
