Query Node-related Configurations

This topic introduces the query node-related configurations of Milvus.

Query node performs hybrid search of vector and scalar data on both incremental and historical data.

Under this section, you can configure query node port, graceful time, etc.

queryNode.gracefulTime

Description Default Value
  • The minimum time before the newly inserted data can be searched.
  • Unit: ms
  • Milvus executes a search request directly when the search message timestamp is earlier the query node system time.
  • When the search message timestamp is later than the query node system time, the Milvus waits until that the time diferrence between query node system time and the timestamp is less than this parameter, and then executes the search request.
  • 0

    TCP port of query node. 21123

    queryNode.grpc.serverMaxRecvSize

    Description Default Value
  • The maximum size of each RPC request that the query node can receive.
  • Unit: Byte
  • 2147483647

    queryNode.grpc.serverMaxSendSize

    Description Default Value
  • The maximum size of each respond the query node can send when receiving an RPC request.
  • Unit: Byte
  • 2147483647
