Request parameters
Parameter | Type | Required | Description | Example |
---|---|---|---|---|
DBInstanceId | string | Yes | The instance ID. You can call the DescribeDBInstances operation to query the instance ID. | rm-bp145737x5bi6**** |
DBProxyEndpointId | string | No | The ID of the proxy endpoint. You can call the DescribeDBProxyEndpoint operation to query the proxy endpoint ID. Note

ConfigDBProxyFeatures | string | No | The features that you want to enable for the proxy endpoint. If you specify more than one feature, separate the features with semicolons (;). Format: Valid feature values:
Valid status values:
Note
If the instance runs PostgreSQL, you can enable only the read/write splitting feature, which is specified by ReadWriteSpliting.

If the latency on a read-only instance exceeds the threshold that you specified, the system no longer forwards read requests to the read-only instance. Unit: seconds If you do not specify this parameter, the original value of this parameter is retained. Valid values: 0 to 3600. Default value: 30. Note
You must specify this parameter only when the read/write splitting feature is enabled.

Note
You must specify this parameter only when the read/write splitting feature is enabled. For more information about the permission allocation policy, see Modify the latency threshold and read weights of ApsaraDB RDS for MySQL instances and Enable and configure the database proxy feature for an ApsaraDB RDS for PostgreSQL instance.
| Standard |
ReadOnlyInstanceWeight | string | No | The read weights of the instance and its read-only instances. A read weight must be a multiple of 100 and cannot exceed 10000. Formats:
| {"rm-uf6wjk5xxxx":"500","rr-tfhfgk5xxx":"200"...} |
DbEndpointOperator | string | No | The type of operation that you want to perform. Valid values:
| Modify |
DbEndpointAliases | string | No | The description of the proxy terminal. | test-proxy |
DbEndpointType | string | No | The type of the proxy terminal. This is a reserved parameter. You do not need to specify this parameter. | RWSplit |
