Vector Database
A specialised database optimised for storing and searching vector embeddings. Essential for RAG and semantic search applications.
In-Depth Explanation
A vector database is a specialised data store optimised for storing, indexing, and querying high-dimensional vector data. Unlike traditional databases that search by exact values, vector databases find similar items based on mathematical distance.
Vector database capabilities:
- Vector storage: Efficiently store millions/billions of embeddings
- Similarity search: Find nearest neighbors quickly
- Metadata filtering: Combine semantic with attribute filters
- Scalability: Handle growing data volumes
- Real-time updates: Add new vectors instantly
Key technologies:
- Indexing algorithms: HNSW, IVF, PQ for fast search
- Distance metrics: Cosine, dot product, Euclidean
- Approximate nearest neighbor: Trade accuracy for speed
- Hybrid search: Combine vector and keyword search
Popular vector databases:
- Managed: Pinecone, Weaviate Cloud, Qdrant Cloud
- Self-hosted: Milvus, Weaviate, Qdrant, Chroma
- Extensions: pgvector (PostgreSQL), Elasticsearch vector
Use cases:
- RAG knowledge bases
- Semantic search engines
- Recommendation systems
- Image/audio similarity
- Anomaly detection
Business Context
Vector databases like Pinecone, Weaviate, and Qdrant enable fast similarity search over millions of embeddings for real-time AI applications.
