I’ve been building a small embedded key-value database in Zig:

https://github.com/lispking/kvdb

It’s a from-scratch project meant to explore storage engine internals in a compact codebase. Right now it has:

* B-tree indexing

* WAL-based durability and crash recovery

* ACID transactions

* 4 KB page-based storage

* in-memory page cache

* zero external dependencies

* a CLI for basic operations

I also added prebuilt binaries and a simple Zig API.

Still very early, but usable enough for experimentation. I’d especially appreciate feedback on the storage/WAL design and what would make a project like this more compelling to other Zig developers.

Thanks.
