Research direction
The issue requests adding HNSW SQ index support to the Go client, similar to the Python client. The Go SDK source is likely in the milvus io/milvus repository under a client directory. Study the existing HNSW index implementation and the Python HNSW SQ support as a template. The issue has two assignees but no linked PR, so confirm if they are actively working on it before starting. Check for any related discussions or branches in the repository.
