update_replicate_configuration()

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

Request syntax

Python

client.update_replicate_configuration(
    clusters: List[dict] = None,
    cross_cluster_topology: List[dict] = None,
    timeout: float = None
)

PARAMETERS:

• clusters (List[dict] | None) -

  A list of cluster configurations. Each dict should contain cluster_id (str), connection_param (dict with uri and token), and optionally pchannels (List[str]).

• cross_cluster_topology (List[dict] | None) -

  A list of replication relationships. Each dict should contain source_cluster_id (str) and target_cluster_id (str).

• timeout (float | None) -

  The timeout duration for this operation. Setting this to None indicates that this operation timeouts when any response arrives or any error occurs.

RETURN TYPE:

Status

EXCEPTIONS:

• ParamError

  This exception will be raised when neither clusters nor cross_cluster_topology is provided.

• MilvusException

  This exception will be raised when the operation fails.

Example

Python

from pymilvus import MilvusClient

client = MilvusClient(
    uri="http://localhost:19530",
    token="root:Milvus"
)

client.update_replicate_configuration(
    clusters=[
        {
            "cluster_id": "source_cluster",
            "connection_param": {
                "uri": "http://source:19530",
                "token": "source_token"
            },
        },
        {
            "cluster_id": "target_cluster",
            "connection_param": {
                "uri": "http://target:19530",
                "token": "target_token"
            },
        }
    ],
    cross_cluster_topology=[
        {
            "source_cluster_id": "source_cluster",
            "target_cluster_id": "target_cluster"
        }
    ]
