CloudRedisClient

CloudRedisClient

Configures and manages Cloud Memorystore for Redis instances

Google Cloud Memorystore for Redis v1beta1

The redis.googleapis.com service implements the Google Cloud Memorystore for Redis API and defines the following resource model for managing Redis instances:

  • The service works with a collection of cloud projects, named: /projects/*
  • Each project has a collection of available locations, named: /locations/*
  • Each location has a collection of Redis instances, named: /instances/*
  • As such, Redis instances are resources of the form: /projects/{project_id}/locations/{location_id}/instances/{instance_id}

Note that location_id must be referring to a GCP region; for example:

  • projects/redpepper-1290/locations/us-central1/instances/my-redis

Constructor

new CloudRedisClient(optionsopt, gaxInstanceopt)

Construct an instance of CloudRedisClient.

Parameters:
Name Type Attributes Description
options object <optional>

The configuration object. The options accepted by the constructor are described in detail in this document. The common options are:

Properties
Name Type Attributes Description
credentials object <optional>

Credentials object.

Properties
Name Type Attributes Description
client_email string <optional>
private_key string <optional>
email string <optional>

Account email address. Required when using a .pem or .p12 keyFilename.

keyFilename string <optional>

Full path to the a .json, .pem, or .p12 key downloaded from the Google Developers Console. If you provide a path to a JSON file, the projectId option below is not necessary. NOTE: .pem and .p12 require you to specify options.email as well.

port number <optional>

The port on which to connect to the remote host.

projectId string <optional>

The project ID from the Google Developer's Console, e.g. 'grape-spaceship-123'. We will also check the environment variable GCLOUD_PROJECT for your project ID. If your app is running in an environment which supports Application Default Credentials, your project ID will be detected automatically.

apiEndpoint string <optional>

The domain name of the API remote host.

clientConfig gax.ClientConfig <optional>

Client configuration override. Follows the structure of gapicConfig.

fallback boolean | "rest" <optional>

Use HTTP fallback mode. Pass "rest" to use HTTP/1.1 REST API instead of gRPC. For more information, please check the documentation.

gaxInstance gax <optional>

loaded instance of google-gax. Useful if you need to avoid loading the default gRPC version and want to use the fallback HTTP implementation. Load only fallback version and pass it to the constructor: const gax = require('google-gax/build/src/fallback'); // avoids loading google-gax with gRPC const client = new CloudRedisClient({fallback: 'rest'}, gax);

Members

apiEndpoint

The DNS address for this API service - same as servicePath(), exists for compatibility reasons.

port

The port for this API service.

scopes

The scopes needed to make gRPC calls for every method defined in this service.

servicePath

The DNS address for this API service.

  callUpgradeInstance();

close() → {Promise}

Terminate the gRPC channel and close the client.

The client will no longer be usable and all future behavior is undefined.

Returns:
Type Description
Promise

A promise that resolves when the client is closed.

getProjectId() → {Promise}

Return the project ID used by this class.

Returns:
Type Description
Promise

A promise that resolves to string containing the project ID.

initialize() → {Promise}

Initialize the client. Performs asynchronous operations (such as authentication) and prepares the client. This function will be called automatically when any class method is called for the first time, but if you need to initialize it before calling an actual method, feel free to call initialize() directly.

You can await on this method if you want to make sure the client is initialized.

Returns:
Type Description
Promise

A promise that resolves to an authenticated service stub.

instancePath(project, location, instance) → {string}

Return a fully-qualified instance resource name string.

Parameters:
Name Type Description
project string
location string
instance string
Returns:
Type Description
string

Resource name string.

listInstancesAsync(request, optionsopt) → {Object}

Equivalent to listInstances, but returns an iterable object.

for-await-of syntax is used with the iterable to get response elements on-demand.

Parameters:
Name Type Attributes Description
request Object

The request object that will be sent.

Properties
Name Type Description
parent string

Required. The resource name of the instance location using the form: projects/{project_id}/locations/{location_id} where location_id refers to a GCP region.

pageSize number

The maximum number of items to return.

If not specified, a default value of 1000 will be used by the service. Regardless of the page_size value, the response may include a partial list and a caller should only rely on response's next_page_token to determine if there are more instances left to be queried.

pageToken string

The next_page_token value returned from a previous ListInstances request, if any.

options object <optional>

Call options. See CallOptions for more details.

Returns:
Type Description
Object

An iterable Object that allows async iteration. When you iterate the returned iterable, each element will be an object representing Instance. The API will be called under the hood as needed, once per the page, so you can stop the iteration when you don't need more results. Please see the documentation for more details and examples.

Example
  /**
   * This snippet has been automatically generated and should be regarded as a code template only.
   * It will require modifications to work.
   * It may require correct/in-range values for request initialization.

    const iterable = await redisClient.listInstancesAsync(request);
    for await (const response of iterable) {
        console.log(response);
    }
  }

  callListInstances();

listInstancesStream(request, optionsopt) → {Stream}

Equivalent to method.name.toCamelCase(), but returns a NodeJS Stream object.

Parameters:
Name Type Attributes Description
request Object

The request object that will be sent.

Properties
Name Type Description
parent string

Required. The resource name of the instance location using the form: projects/{project_id}/locations/{location_id} where location_id refers to a GCP region.

pageSize number

The maximum number of items to return.

If not specified, a default value of 1000 will be used by the service. Regardless of the page_size value, the response may include a partial list and a caller should only rely on response's next_page_token to determine if there are more instances left to be queried.

pageToken string

The next_page_token value returned from a previous ListInstances request, if any.

options object <optional>

Call options. See CallOptions for more details.

Returns:
Type Description
Stream

An object stream which emits an object representing Instance on 'data' event. The client library will perform auto-pagination by default: it will call the API as many times as needed. Note that it can affect your quota. We recommend using listInstancesAsync() method described below for async iteration which you can stop as needed. Please see the documentation for more details and examples.
