updateReplicateConfiguration()

This operation updates replication configuration across Milvus clusters. This is used to configure cross-cluster data replication by defining cluster connections and the replication topology.

Java

public UpdateReplicateConfigurationResp updateReplicateConfiguration(UpdateReplicateConfigurationReq request)

Request Syntax

Java

updateReplicateConfiguration(UpdateReplicateConfigurationReq.builder()
    .replicateConfiguration(ReplicateConfiguration config)
    .build()
);

BUILDER METHODS:

• replicateConfiguration(ReplicateConfiguration config) -

  [REQUIRED]

  The replication configuration containing cluster definitions and topology.

RETURNS:

UpdateReplicateConfigurationResp

EXCEPTIONS:

• MilvusClientException

  This exception will be raised when any error occurs during this operation.
