The default solution for dealing with large amounts of data is server side paging.
This is not always supported and besides that it troubles the and the user because he needs
to flip pages with next and previous buttons, and filtering, sorting and grouping always
require server hits.
On the other hand, if the data is served in one go the user interface gets updated
after the entire dataset is loaded. By using streaming both problems are addressed.
Choose "Streaming" to see the data loaded and parsed as a stream in the browser. The parsed data is page by page added to the controller's scope.
Choose "No streaming" to see the same data read as one file and after the response has loaded added to the scope.
