How do you tune HNSW index parameters (m, efConstruction) for MongoDB Vector Search accuracy?
❓ Interview Prompt: Explain HNSW algorithm parameters, m (links per node), efConstruction (search candidate depth), and recall precision vs build speed trade-offs.
Tuning HNSW vector parameters m (bi-directional links) and efConstruction (candidate depth) balances vector index build latency against k-NN semantic recall precision.
Code Implementation Example
typescript
console.log('Tuning HNSW m=16 and efConstruction=200 optimizes vector recall precision');💡Tuning HNSW parameters for Atlas Vector Search.
🎯 Interview Key Takeaway
Tune HNSW m and efConstruction parameters to achieve optimal recall accuracy for AI vector search queries.
