  63                                 <p>DataTables' server-side processing mode is a feature that naturally fits in with Scroller perfectly.
  64                                 Server-side processing can be used to show large data sets, with the server being used to do the data
  65                                 processing, and Scroller optimising the display of the data in a scrolling viewport.</p>
  66
  67                                 <p>When using server-side processing, Scroller will wait a small amount of time to allow the scrolling
  68                                 to finish before requesting more data from the server (200mS by default). This prevents you from DoSing
  69                                 your own server!</p>
  70
  71                                 <p>This example shows Scroller using server-side processing mode and 5 million rows.
  72                                 <strong>Important</strong> This particular example uses <a href=
  73                                 "//datatables.net/reference/option/ajax"><code class="option" title=
  74                                 "DataTables initialisation option">ajax<span>DT</span></code></a> as a function to 'fake' the data to
  75                                 show Scroller's ability to show large data sets. It does not have a real database behind it! You would
  76                                 normally not use <a href="//datatables.net/reference/option/ajax"><code class="option" title=
  77                                 "DataTables initialisation option">ajax<span>DT</span></code></a> as a function to generate data, but
  78                                 rather as a url for where to fetch the real data!</p>
  79
  80                                 <p>In this example we also enable the <code>loadingIndicator</code> option of Scroller to show the end
  81                                 user what is happening when they scroll passed the currently loaded data.</p>
