set the service endpoint

This sample demonstrates how to set an alternate endpoint when using the BigQuery client libraries.

Code sample

Go

Before trying this sample, follow the Go setup instructions in the BigQuery quickstart using client libraries. For more information, see the BigQuery Go API reference documentation.

To authenticate to BigQuery, set up Application Default Credentials. For more information, see Set up authentication for client libraries.

import (
	"context"
	"fmt"

	"cloud.google.com/go/bigquery"
	"google.golang.org/api/option"
)

// setClientEndpoint creates a bigquery.Client pointing
// to a specific endpoint.
func setClientEndpoint(endpoint, projectID string) (*bigquery.Client, error) {
	// projectID := "my-project-id"
	// endpoint := "https://bigquery.googleapis.com/bigquery/v2/
	ctx := context.Background()
	client, err := bigquery.NewClient(ctx, projectID, option.WithEndpoint(endpoint))
	if err != nil {
		return nil, fmt.Errorf("bigquery.NewClient: %w", err)
	}
	defer client.Close()

	return client, nil
}

Node.js

Before trying this sample, follow the Node.js setup instructions in the BigQuery quickstart using client libraries. For more information, see the BigQuery Node.js API reference documentation.

To authenticate to BigQuery, set up Application Default Credentials. For more information, see Set up authentication for client libraries.

// Import the Google Cloud client library
const {BigQuery} = require('@google-cloud/bigquery');

function setClientEndpoint() {
  // Create a bigquery client pointing to a specific endpoint

  /**
   * TODO(developer): Uncomment the following line of code and fill in your region before running the sample.
   */
  // const region = 'my-region';

  const bigquery = new BigQuery({
    apiEndpoint: `${region}-bigquery.googleapis.com`,
  });

  console.log('API Endpoint:');
  console.log(bigquery.apiEndpoint);
}
