SpannerExecutorProxyClient

Service that executes SpannerActions asynchronously.

Constructor

new SpannerExecutorProxyClient(optionsopt, gaxInstanceopt)

Construct an instance of SpannerExecutorProxyClient.

Parameters:

Name Type Attributes Description

options

object

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

Credentials object.

Properties

Name	Type	Attributes	Description
`client_email`	string	<optional>
`private_key`	string	<optional>

email

string

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

keyFilename

string

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

The port on which to connect to the remote host.

projectId

string

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

The domain name of the API remote host.

clientConfig

gax.ClientConfig

Client configuration override. Follows the structure of gapicConfig.

fallback

boolean

Use HTTP/1.1 REST mode. For more information, please check the documentation.

gaxInstance

gax

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 SpannerExecutorProxyClient({fallback: true}, gax);

Members

Methods

backupPath(project, instance, backup) → {string}

Return a fully-qualified backup resource name string.

Parameters:

Name	Type	Description
`project`	string
`instance`	string
`backup`	string

Returns:

Type	Description
string	Resource name string.

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.

databasePath(project, instance, database) → {string}

Return a fully-qualified database resource name string.

Parameters:

Name	Type	Description
`project`	string

`database`	string

Returns:

Type	Description
string	Resource name string.

databaseRolePath(project, instance, database, role) → {string}

Return a fully-qualified databaseRole resource name string.

Parameters:

Name	Type	Description
`project`	string
`instance`	string
`database`	string
`role`	string

executeActionAsync(optionsopt) → {Stream}

ExecuteActionAsync is a streaming call that starts executing a new Spanner action.

For each request, the server will reply with one or more responses, but only the last response will contain status in the outcome.

Responses can be matched to requests by action_id. It is allowed to have multiple actions in flight--in that case, actions are be executed in parallel.

Parameters:

Name	Type	Attributes	Description
`options`	object	<optional>	Call options. See CallOptions for more details.

Returns:

Type	Description
Stream	An object stream which is both readable and writable. It accepts objects representing SpannerAsyncActionRequest for write() method, and will emit objects representing SpannerAsyncActionResponse on 'data' event asynchronously. Please see the documentation for more details and examples.

Example

include:samples/generated/v1/spanner_executor_proxy.execute_action_async.js

region_tag:spanner-cloud-executor_v1_generated_SpannerExecutorProxy_ExecuteActionAsync_async

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.
