 						<li><code>chunk</code> A callback, much like step, which activates streaming and is executed after every chunk (piece) is loaded and parsed. Works only with local and remote files. Do not use both chunk and step callbacks together. This function can be used to receive results one chunk at a time rather than one row at a time. If your file has a million rows, this results in, say, 10,000 function invocations rather than 1,000,000. In some cases, this may be faster.</li>
