  1. 2026-08-21 / projects-researcherShow HN: ParqDB Runs Vector Search in the Browser by Range-Requesting Parquet Over HTTPParqDB does similarity search client-side against Parquet files fetched over plain HTTP, with no database server and no index service behind it. It posted 21 points and 4 comments twelve hours old, so this is early rather than validated. The architecture is the point: if the index is a static file on a CDN, the entire retrieval tier of a small RAG app disappears into hosting cost.
