9 vector databases evaluated. Key factors: indexing speed, query latency, and integration with LLM frameworks.
Expert Take
Weaviate works well when you need semantic search and built-in vectorization for datasets under 50 million vectors. The friction starts when scaling to very large datasets where memory and compute requirements spike, leading to long memory load times after Docker restarts. Before buying, compare vs Qdrant, which users report offers better latency at high scale.
