Strengths and weaknesses
- +Object-storage-first architecture cuts storage cost to ~$20-70/TB/month versus ~$1,600/TB/month for RAM-resident incumbents
- +Warm query latency competitive with in-memory engines (~10ms p90 vector, ~18ms p90 BM25 on 1M docs)
- +Native hybrid search: dense + sparse vectors, BM25 full-text, attribute filtering, and regex via trigram indexes
- –High cold-query latency (~444ms p90) when a namespace isn't cached, bad for always-must-be-fast workloads
- –Relatively high write latency (~248ms p90 for 512KB upserts) due to object-storage durability path
- –No free tier and a monthly spend minimum, making pgvector cheaper for small/early projects
- +Native hybrid search (HNSW vector + BM25 keyword) with a single query, a standout vs index-only competitors
- +Strong, transparent published ANN benchmarks (e.g. 98.35% recall@10 at ~10,940 QPS on SIFT1M)
- +Built-in vectorizer and generative modules (OpenAI, Cohere, Hugging Face) plus bundled Weaviate Embeddings and Agents
- –Managed cost scales steeply, tens of millions of high-dimensional vectors can run into thousands of dollars per month
- –Pricing model is hard to estimate; metering jargon (vector dimensions, AIUs) makes budgeting difficult, a frequent Reddit/G2 complaint
- –Advanced operations (sharding, schema design, replication tuning) have a steep learning curve for beginners
