Call the ModifyReadOnlyNodeDelayReplicationTime API to configure the delayed replication feature for a read-only node.
Request type
Synchronous request.
Precautions
- Only the read/write endpoints of double node instances support this setting.
- When a read-only node in the instance is associated with other nodes under the same endpoint, configuring replication delay for this read-only node is not supported.
Debug
API Explorer
You can initiate calls online through API Explorer without paying attention to the signature generation process and quickly obtain the call results.
Request parameters
Parameter | Type | Is it required? | Sample value | Description |
InstanceId | String | Yes | mysql-3fb9a5be**** | The Instance ID of the instance to which the read-only node to be queried belongs. |
NodeId | String | Yes | mysql-3fb9a5be****-r3e01 | The Node ID of the read-only node to query. |
DelayReplicationTime | Long | Yes | 1000 | The Data delay time for the read-only node. The value ranges from 0 to 604,800. The unit is Second. tip A value of 0 disables replication delay for the read-only node. |
UpdateEndpointIds | Array of String | Yes | ["mysql-3fb9a5be****-custom-a774","mysql-3fb9a5be****-cluster"] | The ID of the connection endpoint whose association with the read-only node needs to be canceled to set the replication delay. Call the DescribeDBInstanceDetail API to query the connection endpoint associated with the read-only node. tip
