Evaluating HNSW versus disk-based vector search alternatives

Viewed 59
The discussion centers around the effectiveness and practicality of HNSW (Hierarchical Navigable Small World graphs) for vector search, highlighting that while HNSW is popular for its ability to dynamically update with incoming data and avoiding the need for precalculated indexes, it may not scale well for larger datasets. An alternative perspective suggests that many teams prefer the simplicity and operational feasibility of utilizing disk-based solutions, especially when managing millions of vectors, with less focus on complex quantization processes. Comments imply a marketplace underestimation of the necessity for advanced vector databases, advocating instead for solutions that optimize immediate usability without heavy computational demands. Furthermore, a recurring theme is the potential benefit of simplified methods that allow for real-time updates and efficient filtering.
