Our customer use Doubleclick Campaign Manager, and Doubleclick Bid Manager.
That product can export reporting data(e.g., impression, click, conversion, etc) to Google Cloud Storage.
We can import the data on GCS by using DataConnector.
The customer feels export timing to GCS from these products is unstable, so they afraid of that they need to retry import job many times.
If we build gcs_wait function like an s3_wait, it would be helpful for them.
