Show HN: A lightweight, stateless database for agent memory
Summary
The post argues for moving agent memory storage to the edge with a deterministic, typed memory store. It introduces polign_db, a lightweight, serverless database built on top of a hybrid vector + BM25 engine that runs in local object storage and preserves memory across restarts. The piece outlines design principles, presents a low-footprint demo, and discusses tradeoffs between model-driven memory and schema-driven memory, plus practical deployment steps and a live demo.
