Vector search just got up to 10x faster and vertically scalable

• Weaviate

  76 9,436 10.0 Go

  Weaviate is an open-source vector database that stores both objects and vectors, allowing for the combination of vector search with structured filtering with the fault tolerance and scalability of a cloud-native database​.

  

I'm affiliated with Weaviate, so maybe nice to get this out here for the record :)

We call Weaviate a "vector search engine" (i.e., we prefer "vector search engine" because it describes the type of database) since around Aug, 2020

Github: https://github.com/semi-technologies/weaviate/tree/a3967aff5...

The reason was simple; our community started to say that the mixed vector and scalar filter search capabilities were what they liked most.

Also, our benchmarks are available for quite some time here: https://weaviate.io/developers/weaviate/current/benchmarks/a...

They are based on ann-benchmarks.com but adjusted for full databases.

• knowhere

  1 181 3.5 C++

  Discontinued Knowhere is an open-source vector search engine, integrating FAISS, HNSW, etc.

  

Just to clarify, Milvus is much more than a wrapper around FAISS. Our vector search component called Knowhere (https://github.com/milvus-io/knowhere) utilizes FAISS and Annoy and will soon include ScaNN, DiskANN, and in-house vector indexes as well. Milvus then uses Knowhere as the compute engine, and implements a variety of database functions such as horizontal scaling, caching, replication, failover, and object storage on top of Knowhere. If you're interested, I recommend checking out our architecture page (https://milvus.io/docs/architecture_overview.md).
