Query Node-related Configurations Milvus documentation

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

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.

`queryNode.port`

Description	Default Value
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

`queryNode.grpc.clientMaxRecvSize`

Description	Default Value
The maximum size of each respond that the query node can receive when sending an RPC request. Unit: Byte	104857600

`queryNode.grpc.clientMaxSendSize`

Description	Default Value
The maximum size of each RPC request that the query node can send. Unit: Byte	104857600

`queryNode.replicas`

Description	Default Value
The number of in-memory replicas of data segments that are created on query nodes when a collection is loaded. In a Standalone deployment, the maximum value is 1. For more information, refer to In-Memory Replica.	1

`queryNode.stats.publishInterval`

Description	Default Value
The interval that query node publishes the node statistics information, including segment status, cpu usage, memory usage, health status, etc. Unit: ms	1000

`queryNode.dataSync.flowGraph.maxQueueLength`

Description	Default Value
The maximum size of task queue cache in flow graph in query node. Unit: MB Query node uses flow graph to subscribe to and organize the message flow.	1024

`queryNode.segcore.chunkRows`

Description	Default Value
Row count by which Segcore divides a segment into chunks.	1024

`queryNode.segcore.InterimIndex`

Description	Default Value
Whether to create a temporary index for growing segments and sealed segments not yet indexed, improving search performance. Milvus will eventually seals and indexes all segments, but enabling this optimizes search performance for immediate queries following data insertion. This defaults to `true`, indicating that Milvus creates temporary index for growing segments and the sealed segments that are not indexed upon searches.	true

Milvus will eventually seals and indexes all segments, but enabling this optimizes search performance for immediate queries following data insertion.
This defaults to `true`, indicating that Milvus creates temporary index for growing segments and the sealed segments that are not indexed upon searches.
