BatANN is a distributed, disk-based vector search system designed for high-throughput approximate nearest neighbor (ANN) queries at scale. It addresses the challenge of performing efficient vector similarity search when vectors cannot fit entirely in memory, making it highly relevant for large-scale vector database systems.
This system provides architectural patterns and methods applicable to the internal design of vector databases that need to handle more vectors than can fit in RAM, offering a cost-effective alternative to memory-only ANN search systems.
