Understanding Pgvector's HNSW Index Storage in Postgres
In this article, we'll explore how pgvector works under the hood, focusing on how the HNSW index is stored in Postgres.
magicNumber → constant which is 0xA953A953 hex number, used to detect early potential header corruption or accidental page structure mismatch. Let’s try to visualize the connections of index tuples by mapping structs to JSON representations to better understand what is happening under the hood. We ported this parser to WASM and built an interactive demo using PGlite to better visualize the storage layout of pgvector’s HNSW index.
