The CIDR block of the DLI queue that is bound with a datasource connection cannot overlap with that of the data source.
The default queue cannot be bound with a connection.

Before using an enhanced datasource connection, you must bind a queue and ensure that the VPC peering connection is in the Active state.

Method 1
In the Enhanced tab, select a connection and click Bind Queue in the Operation column. In the dialog box that is displayed, select the queues to be bound and click OK.

Method 2
Click the name of the selected connection. The Details page is displayed. Click Create in the upper left corner. In the dialog box that is displayed, select the queues to be bound and click OK.

On the Enhanced tab page, select a connection and click the connection name to view the information about the bound queue.

Parameter	Description
VPC Peering ID	ID of the VPC peering connection created in the cluster to which the queue belongs. NOTE: A VPC peering connection is created for each queue bound to an enhanced datasource connection. The VPC peering connection is used for cross-VPC communication. Ensure that the security group used by the data source allows access from the DLI queue CIDR block, and do not delete the VPC peering connection during the datasource connection.
Name	Name of a bound queue.
Connection Status	Datasource connection status. The following three statuses are available: Creating Active Failed NOTE: If the connection status is Failed, click on the left to view the detailed error information.
Updated	Time when a connection is updated. The connections in the connection list can be displayed according to the update time in ascending or descending order.
