Controlling page size

Collections automatically handle paging through results, but you may want to control the number of items returned from a single service operation call. You can do so using thepage_size() method:

# S3 iterate over all objects 100 at a timefor obj in bucket.objects.page_size(100): print(obj.key)

By default, S3 will return 1000 objects at a time, so the above code would let you process the items in smaller batches, which could be beneficial for slow or unreliable internet connections.
