ApsaraDB RDS：ModifyDBProxyEndpoint

The instance ID. You can call the DescribeDBInstances operation to query the instance ID.

The ID of the proxy endpoint. You can call the DescribeDBProxyEndpoint operation to query the proxy endpoint ID.

The features that you want to enable for the proxy endpoint. If you specify more than one feature, separate the features with semicolons (;). Format: Feature 1:Status;Feature 2:Status;.... Do not add a semicolon (;) at the end of the value.

Valid feature values:

• ReadWriteSpliting: read/write splitting
• ConnectionPersist: connection pooling
• TransactionReadSqlRouteOptimizeStatus: transaction splitting

Valid status values:

• 1: enabled
• 0: disabled

The region ID. You can call the DescribeRegions operation to query the most recent region list.

The latency threshold that is allowed for read/write splitting. 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.

The policy that is used to allocate read weights. Valid values:

• Standard: The system automatically allocates read weights to the instance and its read-only instances based on the specifications of the instances.
• Custom: You must manually allocate read weights to the instance and its read-only instances.

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:

• Standard instance: {"ID of the primary instance":"Weight","ID of the read-only instance":"Weight"...}

  Example: {"rm-uf6wjk5****":"500","rr-tfhfgk5xxx":"200"...}

• Instance on RDS Cluster Edition: {"ID of the read-only instance":"Weight","DBClusterNode":{"ID of the primary node":"Weight","ID of the secondary node":"Weight","ID of the secondary node":"Weight"...}}

  Example: {"rr-tfhfgk5****":"200","DBClusterNode":{"rn-2z****":"0","rn-2z****":"400","rn-2z****":"400"...}}

  Note DBClusterNode is required if the instance runs RDS Cluster Edition. The DBClusterNode parameter includes information about IDs and weights of the primary and secondary nodes..

The type of operation that you want to perform. Valid values:

• Modify: Modify a proxy terminal. This is the default value.
• Create: Create a proxy terminal.
• Delete: Delete a proxy terminal.

The description of the proxy terminal.

The type of the proxy terminal. This is a reserved parameter. You do not need to specify this parameter.

The read and write attributes of the proxy terminal. Valid values:

• ReadWrite: The proxy terminal connects to the primary instance and can receive both read and write requests.
• ReadOnly: The proxy terminal does not connect to the primary instance and can receive only read requests. This is the default value.

A deprecated parameter. You do not need to specify this parameter.

Specifies the switch ID corresponding to the availability zone of the proxy connection address. By default, it is the switch ID corresponding to the default terminal of the proxy instance. You can query the created switch by calling the DescribeVSwitches interface.

Effective time, value:

• Immediate: effective immediately.

• MaintainTime: effective during the operational and maintainable time period, see ModifyDBInstanceMaintainTime.

• SpecificTime: effective at a specified time.

Default value: MaintainTime.

The specified time takes effect. Format: yyyy-MM-ddTHH:mm:ssZ (UTC time).
