Edge Security Acceleration:PutKvWithHighCapacity

Last Updated:Mar 19, 2026

Set a single high-capacity key-value pair in a KV namespace. This operation supports values up to 25 MB.

Operation description

This interface provides the same functionality as PutKv, but supports larger request bodies. If your request body is small, use the PutKv interface instead to reduce server-side processing time. Call this interface using an SDK. For example, with the Go SDK, call the PutKvWithHighCapacityAdvance function.

func TestPutKvWithHighCapacity() {
	// Configure initialization
	cfg := new(openapi.Config)
	cfg.SetAccessKeyId("xxxxxxxxx")
	cfg.SetAccessKeySecret("xxxxxxxxxx")
	cli, err := NewClient(cfg)
	if err != nil {
		return err
	}
	runtime := &util.RuntimeOptions{}

	// Construct the key-value pair request to be uploaded
	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 larger than 2 MB, call the high-capacity interface to 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
}
