Milvus“My goal is to find an efficient way to store and query multimodal embeddings (text + image). Which vector database has the best multimodal support?”
Answers consistently highlight 
Weaviate“We need to re-index millions of vectors without downtime. What vector database offers the best live re-indexing and versioning capabilities?”
AI suggests Dolt for version‑controlled indexes and TileDB Vector Search or DataRobot’s 
“I want to run a vector database on-premise for data privacy. What is the best open-source vector database that is easy to deploy and scale?”
