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.

Warning

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

Specify the prefix to delete only objects whose keys begin with the specified prefix.

 

Delimiter

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

Warning

If you select the Delete object from bucket list check box, the Key prefix and Delimiter fields as well as the Specify project ID check box will not be available.

Advanced settings

tStatCatcher Statistics

Select this check box to gather the Job processing metadata at the Job level as well as at each component level.

Global Variables

NB_LINE: the number of rows read by an input component or transferred to an output component. This is an After variable and it returns an integer.

ERROR_MESSAGE: the error message generated by the component when an error occurs. This is an After variable and it returns a string. This variable functions only if the Die on error check box is cleared, if the component has this check box.

A Flow variable functions during the execution of a component while an After variable functions after the execution of the component.

To fill up a field or expression with a variable, press Ctrl + Space to access the variable list and choose the variable to use from it.

For further information about variables, see Talend Studio User Guide.

Usage

This component can be used together with the tGSList component to check if the objects which match the specified criteria are deleted successfully.
