(SQL Server) Amazon S3 List More than 1000 Objects in Bucket

See more Amazon S3 Examples

S3 limits the size of the "List Objects" response to 1000 objects. To retrieve a listing of all of the objects in a bucket containing more than 1000 objects, we'll need to send several requests using continuation tokens.
