Edge Security Acceleration:PutKvWithHighCapacity

Last Updated:Nov 15, 2025

Configures a large key-value pair for a namespace. The request body can be up to 25 MB.

Operation description

This operation allows you to upload a larger request body than by using PutKv . For small request bodies, we recommend that you use PutKv to minimize the server processing time. This operation must be called by using SDKs. The following sample code uses the Golang SDK and PutKvWithHighCapacityAdvance to call the operation.

func TestPutKvWithHighCapacity() {
	// Initialize the configurations.
	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 for uploading key-value pairs.
	namespace := "test-put-kv"
	key := "test_PutKvWithHighCapacity_0"
	value := strings.Repeat("t", 10*1024*1024)
	rawReq := &PutKvRequest{
		Namespace: &namespace,
		Key:       &key,
		Value:     &value,
	}
	payload, err := json.Marshal(rawReq)
	if err != nil {
		return err
	}

	// If the payload is greater than 2 MB, call the PutKvWithHighCapacity operation for upload.
	reqHighCapacity := &PutKvWithHighCapacityAdvanceRequest{
		Namespace: &namespace,
		Key:       &key,
		UrlObject: bytes.NewReader([]byte(payload)),
	}

	resp, err := cli.PutKvWithHighCapacityAdvance(reqHighCapacity, runtime)
	if err != nil {
		return err
	}
	return nil
}

Debugging

You can run this interface directly in OpenAPI Explorer, saving you the trouble of calculating signatures. After running successfully, OpenAPI Explorer can automatically generate SDK code samples.

Authorization information

The following table shows the authorization information corresponding to the API. The authorization information can be used in the Action policy element to grant a RAM user or RAM role the permissions to call this API operation. Description:

  • Operation: the value that you can use in the Action element to specify the operation on a resource.
  • Access level: the access level of each operation. The levels are read, write, and list.
  • Resource type: the type of the resource on which you can authorize the RAM user or the RAM role to perform the operation. Take note of the following items:
    • For mandatory resource types, indicate with a prefix of * .
    • If the permissions cannot be granted at the resource level, All Resources is used in the Resource type column of the operation.
  • Condition Key: the condition key that is defined by the cloud service.
  • Associated operation: other operations that the RAM user or the RAM role must have permissions to perform to complete the operation. To complete the operation, the RAM user or the RAM role must have the permissions to perform the associated operations.
