A distributed vector retrieval system and method

Abstract

The embodiment of the present invention discloses a distributed vector retrieval system, including: a master node group, including a plurality of master nodes, one is a leader node, the leader node assigns the index table fragments to the designated vector node group, and the leader node assigns its data Synchronize to other master nodes; multiple vector node groups, each vector node group includes multiple vector nodes, each vector node stores vector data and index table fragmentation, each vector node responds to requests from routing nodes, and retrieves data or Synchronize data; the routing node group includes multiple routing nodes, each routing node sends the request to the corresponding vector node group, and returns the retrieval results; the index data maintenance tool writes the index vector data into the index message queue according to the request, according to The message type calls a routing node. The embodiment of the invention also discloses a distributed vector retrieval method. The present invention can ensure the consistent update of offline and online index data under the condition of high concurrent access.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a distributed vector retrieval system and method. Background technique [0002] The distributed vector retrieval system in the prior art, in the case of high concurrent access, the response time is relatively slow, or there is a downtime, and the online real-time index vector data and the offline batch index vector data cannot be updated consistently, resulting in The index vector data is inconsistent, affecting the reliability of the retrieval system. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide a distributed vector retrieval system and method, which can ensure consistent update of offline and online index vector data under high concurrent access conditions. [0004] An embodiment of the present invention provides a distributed vector retrieval system, the system comprising: [0005] The ...
