title: Listing all files in a Google Cloud Storage bucket and its pricing
body: <p>When using the <a href="https://cloud.google.com/nodejs/docs/reference/storage/1.3.x/Bucket#getFilesStream" rel="nofollow noreferrer">bucket.getFilesStream</a>, which auto-paginates through the files in a bucket, is each page's worth of data request considered single Class A operations? Or is the entire stream using pagination considered a single Class A operation?</p>
  
  <p>If it's multiple operations, is there a cheaper way to get a list of all files in a bucket, assuming there are millions of files?</p>
