Show HN: ParqDB – Vector search in the browser from Parquet over HTTP
Summary
ParqDB enables vector search directly in the browser by embedding Wikipedia articles with MiniLM and indexing them as immutable Parquet files stored in object storage. The browser reads only required byte ranges via HTTP Range and performs ranking in WASM, ensuring no query server sees user data. This showcases a privacy-preserving, client-side approach to vector search using Parquet over HTTP and WASM in the browser.
