Description

Hello, Do you support or plan on supporting SQ compression? I see you support PQ compression. FAISS also supports milder SQ compression which for my use-cases works better. Wondering if this is on the road map. If not, where could I look to adding it?

Contributor guide

Research direction
Study the existing PQ compression implementation in the lance codebase, then identify where to add SQ as an alternative compression method. Look at the IVF index code to understand how compression is integrated.
