Vearch is a scalable distributed system for efficient similarity search of deep learning vectors.

• Data Model

  space, documents, vectors, scalars

• Components

  Master, Router and PartitionServer

• Master

  Responsible for schema mananagement, cluster-level metadata, and resource coordination.

• Router

  Provides RESTful API: create , delete search and update ; request routing, and result merging.

• PartitionServer (PS)

  Hosts document partitions with raft-based replication.

  Gamma is the core vector search engine implemented based on faiss. It provides the ability of storing, indexing and retrieving the vectors and scalars.

• Quickly build a distributed vector search system with RESTful API, please see docs/Deploy.md.

• Vearch can be leveraged to build a complete visual search system to index billions of images. The image retrieval plugin for object detection and feature extraction is also required. For more information, please refer to docs/Quickstart.md.
