<p>how adaptable will the fast CSV loader be to other formats, like ARFF, txt, matrix market, and anything else we might choose to support in the future?</p>

<p>They could be supported in the future.</p>

<blockquote>
<p>so we either need to write our own tests for everything, since the fast CSV library doesn't have any tests I can see.</p>

<p>I am planning on writing some tests for csv parser too, maybe on this week.</p>

<p>This is a prototype, showing one of the possible solution to optimize loading time. There are still many things to do before it really work.</p>
