BatchDeleteDcdnKvWithHighCapacity - Edge Security Acceleration

Deletes multiple key-value pairs from a specified KV namespace based on a list of keys. The maximum size of the request body is 100 MB.

Operation description

This operation provides the same features as BatchDeleteDcdnKv but supports a larger request body. If your request body is small, use the BatchDeleteDcdnKv operation to reduce server-side processing time. You must use an SDK to call this operation. For example, if you use the Go SDK, you must call the BatchDeleteDcdnKvWithHighCapacityAdvance function.

func TestBatchDeleteWithHighCapacity() error {
	// Initialize the configuration.
	cfg := new(openapi.Config)
	cfg.SetAccessKeyId("xxxxxxxxx")
	cfg.SetAccessKeySecret("xxxxxxxxxx")
	cli, err := NewClient(cfg)
	if err != nil {
		return err
	}
	runtime := &util.RuntimeOptions{}

	// Construct a request to batch delete key-value pairs.
	namespace := "test_batch_put"
	rawReq := BatchDeleteDcdnKvRequest{
		Namespace: &namespace,
	}
	for i := 0; i < 10000; i++ {
		key := fmt.Sprintf("test_key_%d", i)
		rawReq.Keys = append(rawReq.Keys, &key)
	}
	payload, err := json.Marshal(rawReq)
	if err != nil {
		return err
	}

	// If the payload is larger than 2 MB, call the high-capacity operation to delete the key-value pairs.
	reqHighCapacity := BatchDeleteDcdnKvWithHighCapacityAdvanceRequest{
		Namespace: &namespace,
		UrlObject: bytes.NewReader(payload),
	}
	resp, err := cli.BatchDeleteDcdnKvWithHighCapacityAdvance(&reqHighCapacity, runtime)
	if err != nil {
		return err
	}
	return nil
}

Test

RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.
API: The API that you can call to perform the action.
Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.
Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.
- For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.
- For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.
Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.
Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.
