Description

We can use scalar quantization for ivf(even better for hnsw)

Contributor guide

Research direction
Study scalar quantization techniques in vector databases (e.g., FAISS). Understand how IVF and HNSW indexing work. Identify where quantization can be applied to reduce memory or speed up search. Propose a design and implement the quantization for IVF/HNSW.
