Can I use this skill with Qdrant?

Yes, this skill provides specific templates for Qdrant collection configurations, including optimizer and quantization settings tailored for different use cases.

What index is best for over 100 million vectors?

For datasets exceeding 100 million vectors, it is generally recommended to use IVF combined with Product Quantization (PQ) or DiskANN to manage memory constraints effectively.

HNSW tuning involves adjusting parameters like M (connections per node) and ef_construction (build quality) to find the optimal balance between search speed, memory usage, and retrieval accuracy.

How does efSearch affect search performance?

A higher efSearch value increases search accuracy (recall) by exploring more of the HNSW graph, but it also increases the search latency per query.

When should I use quantization for my vectors?

You should consider quantization when your vector index exceeds available RAM, when you need to reduce storage costs, or when you are scaling beyond 1 million vectors.
