Break and stop the pagination if we have the results

[Fokko]

Hi Googlers,

I would like to suggest the following optimization. Right now the while loop will continue to fetch results while we already have the max results. For example, will become very inefficient when you're looking if a directory exists, and it will fetch all the pages.

This caused our cluster to do 10th of thousands of requests per second, which became quite expensive.

Regards, Fokko

Thank you for contribution.

I think that we mitigated spike in the list requests in newly released GCS connector 1.9.15 (see issue #151), but this will be worthwhile improvement anyway, please allow us some time to review it.

Thanks for the quick response. I'll try to fix the tests somewhere today.
