Vector Index Tuning FAQs

Question 1

Does this skill support specific vector databases like Qdrant?

Accepted Answer

Yes, it includes specialized templates for configuring Qdrant collections and general patterns applicable to libraries like hnswlib and FAISS.

Question 2

When should I use vector quantization?

Accepted Answer

Quantization is recommended when your vector data exceeds available RAM or when you need to reduce infrastructure costs. Strategies like Product Quantization (PQ) can reduce memory usage by up to 95%.

Question 3

How do I calculate search recall for my vector index?

Accepted Answer

The skill provides benchmarking templates that compare your index's approximate nearest neighbor results against a brute-force exact search ground truth to determine recall accuracy.

Question 4

What index type is best for my data size?

Accepted Answer

Generally, use Flat indexes for <10K vectors, HNSW for 10K-1M, HNSW with quantization for 1M-100M, and IVF with PQ or DiskANN for datasets exceeding 100M vectors.

Question 5

What parameters are most important for HNSW tuning?

Accepted Answer

The most critical parameters are M (number of bidirectional links), efConstruction (index build quality), and efSearch (search accuracy). This skill helps you balance these to optimize for your specific dataset size.
