Vector Database

A Vector Database is a system built to store embedding vectors and search them by similarity at scale, using approximate nearest-neighbor (ANN) indexes to return the closest matches in milliseconds across millions of items.

Beyond raw similarity it handles the production concerns builders care about: metadata filtering, hybrid lexical-plus-vector queries, updates and deletes, sharding, and persistence. It is the storage and retrieval layer beneath most RAG and semantic-search systems.

The core tradeoff is recall versus latency and cost: ANN indexes approximate, so tuning hard for speed silently drops relevant results. Filtering and freshness needs often constrain index choice more than raw query speed does.
