These properties are used to configure tGSList running in the Standard Job framework.

The Standard tGSList component belongs to the Big Data and the Cloud families.

The component in this framework is available in all Talend products.

Basic settings

Use an existing connection

Select this check box and in the Component List click the relevant connection component to reuse the connection details you already defined.

Access Key and Secret Key

Type in the authentication information obtained from Google for making requests to Google Cloud Storage.

These keys can be consulted on the Interoperable Access tab view under the Google Cloud Storage tab of the project from the Google APIs Console.

To enter the secret key, click the [...] button next to the secret key field, and then in the pop-up dialog box enter the password between double quotes and click OK to save the settings.

For more information about the access key and secret key, go to https://developers.google.com/storage/docs/reference/v1/getting-startedv1?hl=en/ and see the description about developer keys.

The Access Key and Secret Key fields will be available only if you do not select the Use an existing connection check box.

Specify project ID

Select this check box and in the Project ID field enter the project ID from which you want to retrieve a list of objects.

List objects in bucket list

  • Key prefix: type in the prefix to list only objects whose keys begin with the specified string in the specified bucket.

  • Delimiter: type in the delimiter to list only those objects with key names up to the delimiter.
