- The article discusses the current state of vector search in SQLite, highlighting the need for memory-efficient, fast, and simple solutions.
- Existing options like sqlite-vss, sqlite-vec, and libsql are reviewed, each with their own limitations such as integration issues, complex queries, or long indexing times.
- A new solution, sqlite-vector, is introduced, focusing on optimized brute-force search, hardware-specific distance functions, and support for various data types.
- Benchmark results show sqlite-vector outperforms sqlite-vec in insert and query times, especially with quantization and preloading, while maintaining low memory usage.
- The article emphasizes the importance of lightweight, efficient, and SQL-integrated vector search for the SQLite community and invites feedback from developers experimenting with vector search.
