Show HN: Kvdb – a lightweight embedded key-value database written in Zig
Hi HN,<p>I’ve been building a small embedded key-value database in Zig:<p><a href="https://github.com/lispking/kvdb" rel="nofollow">https://github.com/lispking/kvdb</a><p>It’s a from-scratch project meant to explore storage engine internals in a compact codebase. Right now it has:<p>* B-tree indexing<p>* WAL-based durability and crash recovery<p>* ACID transactions<p>* 4 KB page-based storage<p>* in-memory page cache<p>* zero external dependencies<p>* a CLI for basic operations<p>I also added prebuilt binaries and a simple Zig API.<p>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.<p>Thanks.
Kvdb is currently a technical proof-of-concept for a storage engine rather than a commercial startup, facing an uphill battle against deeply entrenched incumbents like SQLite and RocksDB. While the choice of Zig is modern and the technical implementation of ACID properties is a good signal, there is no evidence of a business model, team pedigree, or significant market differentiation yet.
