Weaviate pros and cons
Auto-vectorization at insert time means developers don't need to manage embedding pipelines separately — Weaviate calls the embedding model and stores the result automatically.
Hybrid search combining dense vector + BM25 keyword search in a single query outperforms pure vector search on most real-world information retrieval tasks.
Open-source BSD license allows full self-hosting with zero per-query costs — significant cost advantage for high-query-volume applications.
Native multi-tenancy makes it suitable for SaaS applications where each customer's data must be isolated in a shared database.
Memory-intensive HNSW indexing can require significant RAM for large datasets — teams indexing billions of vectors need careful infrastructure planning.
GraphQL API has a steeper learning curve than pure REST interfaces; developers unfamiliar with GraphQL take longer to become productive.
