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

Valid capability values:

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

Valid status values:

• 1: enabled
• 0: disabled

• If the instance runs PostgreSQL, you can enable only read/write splitting, which is specified by ReadWriteSpliting.

• Nearest access is supported only by dedicated database proxies for RDS instances that run MySQL.

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 (default): The system automatically assigns read weights to the primary and read-only instances based on the specifications of these instances.
• Custom: You must manually allocate read weights to the primary and 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.

The ID of the vSwitch in the zone in which the proxy endpoint is specified. The default value is the ID of the vSwitch that corresponds to the default terminal of the database proxy. You can call the DescribeVSwitches operation to query existing vSwitches.

The effective time. Valid values:

• Immediate: The effective time is immediate.
• MaintainTime: The effective time is within the maintenance window. For more information, see ModifyDBInstanceMaintainTime.
• SpecificTime: The effective time is a specified point in time.

Default value: MaintainTime.

The point in time that you want to specify. Specify the time in the ISO 8601 standard in the yyyy-MM-ddTHH:mm:ssZ format. The time must be in UTC.
