Credentials and Project ID

A new attribute to drag and drop a Google Cloud Platform Credentials Metadata node on the BigQuery Metadata has been added, to replace the usage of 'credentialsFile' and 'projectId' properties which are now deprecated.

Note that for backward compatibility, when properties are defined they have priority on the new credentials link.

To use the new mechanism, you must remove the properties and then define the link.

 

Refer to this article for more information.

 

Temporary Bucket

A new attribute to drag and drop a Google Cloud Storage Bucket Metadata node has been added, to replace the default storage bucket attribute which is now deprecated.

Note that for backward compatibility, when the old attribute is defined, it has priority on the new storage link.
