getJobExecutionDetails(request, options)

getJobExecutionDetails(request?: protos.google.dataflow.v1beta3.IGetJobExecutionDetailsRequest, options?: CallOptions): Promise<[
        protos.google.dataflow.v1beta3.IStageSummary[],
        protos.google.dataflow.v1beta3.IGetJobExecutionDetailsRequest | null,
        protos.google.dataflow.v1beta3.IJobExecutionDetails
    ]>;

Request detailed information about the execution status of the job.

EXPERIMENTAL. This API is subject to change or removal without notice.

Parameters

Name	Description
request	`protos.google.dataflow.v1beta3.IGetJobExecutionDetailsRequest` The request object that will be sent.
options	`CallOptions` Call options. See CallOptions for more details.

Returns

Type Description

Promise<[ protos.google.dataflow.v1beta3.IStageSummary[], protos.google.dataflow.v1beta3.IGetJobExecutionDetailsRequest | null, protos.google.dataflow.v1beta3.IJobExecutionDetails ]>

{Promise} - The promise which resolves to an array. The first element of the array is Array of [StageSummary]. The client library will perform auto-pagination by default: it will call the API as many times as needed and will merge results from all the pages into this array. Note that it can affect your quota. We recommend using getJobExecutionDetailsAsync() method described below for async iteration which you can stop as needed. Please see the [documentation](https://github.com/googleapis/gax-nodejs/blob/master/client-libraries.md#auto-pagination) for more details and examples.

getJobExecutionDetailsAsync(request, options)

getJobExecutionDetailsAsync(request?: protos.google.dataflow.v1beta3.IGetJobExecutionDetailsRequest, options?: CallOptions): AsyncIterable<protos.google.dataflow.v1beta3.IStageSummary>;

Equivalent to getJobExecutionDetails, but returns an iterable object.

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

Parameters

Name	Description
request	`protos.google.dataflow.v1beta3.IGetJobExecutionDetailsRequest` The request object that will be sent.
options	`CallOptions` Call options. See CallOptions for more details.

Returns

Type

Description

AsyncIterable<protos.google.dataflow.v1beta3.IStageSummary>

{Object} An iterable Object that allows [async iteration](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Iteration_protocols). When you iterate the returned iterable, each element will be an object representing [StageSummary]. 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](https://github.com/googleapis/gax-nodejs/blob/master/client-libraries.md#auto-pagination) for more details and examples.

Example


  /**
   * TODO(developer): Uncomment these variables before running the sample.
   */
  /**
   *  A project id.
   */
  // const projectId = 'abc123'
  /**
   *  The job to get execution details for.
   */
  // const jobId = 'abc123'
  /**
   *  The regional endpoint 
   *  (https://cloud.google.com/dataflow/docs/concepts/regional-endpoints) that
   *  contains the job specified by job_id.
   */
  // const location = 'abc123'
  /**
   *  If specified, determines the maximum number of stages to
   *  return.  If unspecified, the service may choose an appropriate
   *  default, or may return an arbitrarily large number of results.
   */
  // const pageSize = 1234
  /**
   *  If supplied, this should be the value of next_page_token returned
   *  by an earlier call. This will cause the next page of results to
   *  be returned.
   */
  // const pageToken = 'abc123'

  // Imports the Dataflow library
  const {MetricsV1Beta3Client} = require('@google-cloud/dataflow').v1beta3;

  // Instantiates a client
  const dataflowClient = new MetricsV1Beta3Client();

  async function callGetJobExecutionDetails() {
    // Construct request
    const request = {
    };

    // Run request
    const iterable = await dataflowClient.getJobExecutionDetailsAsync(request);
    for await (const response of iterable) {
        console.log(response);
    }
  }

  callGetJobExecutionDetails();

getJobExecutionDetailsStream(request, options)

getJobExecutionDetailsStream(request?: protos.google.dataflow.v1beta3.IGetJobExecutionDetailsRequest, options?: CallOptions): Transform;

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

Parameters

Name	Description
request	`protos.google.dataflow.v1beta3.IGetJobExecutionDetailsRequest` The request object that will be sent.
options	`CallOptions` Call options. See CallOptions for more details.

Returns

Type Description

Transform

{Stream} An object stream which emits an object representing [StageSummary] 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 getJobExecutionDetailsAsync() method described below for async iteration which you can stop as needed. Please see the [documentation](https://github.com/googleapis/gax-nodejs/blob/master/client-libraries.md#auto-pagination) for more details and examples.

getJobMetrics(request, options)

getJobMetrics(request?: protos.google.dataflow.v1beta3.IGetJobMetricsRequest, options?: CallOptions): Promise<[
        protos.google.dataflow.v1beta3.IJobMetrics,
        protos.google.dataflow.v1beta3.IGetJobMetricsRequest | undefined,
        {} | undefined
    ]>;

Request the job status.

To request the status of a job, we recommend using projects.locations.jobs.getMetrics with a [regional endpoint] (https://cloud.google.com/dataflow/docs/concepts/regional-endpoints). Using projects.jobs.getMetrics is not recommended, as you can only request the status of jobs that are running in us-central1.

Parameters

Name	Description
request	`protos.google.dataflow.v1beta3.IGetJobMetricsRequest` The request object that will be sent.
options	`CallOptions` Call options. See CallOptions for more details.

Returns

Type	Description
Promise<[ protos.google.dataflow.v1beta3.IJobMetrics, protos.google.dataflow.v1beta3.IGetJobMetricsRequest \| undefined, {} \| undefined ]>	{Promise} - The promise which resolves to an array. The first element of the array is an object representing [JobMetrics]. Please see the [documentation](https://github.com/googleapis/gax-nodejs/blob/master/client-libraries.md#regular-methods) for more details and examples.

Example


  /**
   * TODO(developer): Uncomment these variables before running the sample.

  /**
   *  A project id.

initialize()

initialize(): Promise<{
        [name: string]: Function;
    }>;

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<{ [name: string]: Function; }>	{Promise} A promise that resolves to an authenticated service stub.
