Hi everyone! I’m working on Transit ([Data, computation and policies | Transit](https://spoke-sh.github.io/transit)), a versioned database and durable execution runtime written in Zig.

It brings together tables, key-value storage, documents, streams and queues, with a query engine called Fuze and a durable application framework called Station. There’s also a SQL console, a browser interface called Board, and SDKs for several languages.

A few parts of the implementation might be interesting:

It’s early days but feel free to drop thoughts and comments if you find it useful or interesting.

Currently pinned to Zig 0.17.0-dev.2267+48abf1a34. The repository’s Nix development environment provides the pinned toolchain.

I use AI for architecture, implementation, tests and documentation. Its involvement spans the project.
