SNKV is an embedded key-value store built directly on SQLite's B-tree storage engine, bypassing the SQL layer for lower overhead while maintaining ACID compliance. It's interesting because it combines battle-tested SQLite reliability with modern KV features like TTL, column families, vector search, and transparent encryption in a lightweight C library.

Target audience: backend devs, embedded systems engineers, data engineers
