            <b>snorkel</b> answers questions about the <b>here</b> and
            <b>now</b>.  You can think of snorkel like an <a
            href="http://en.wikipedia.org/wiki/Online_analytical_processing">OLAP</a>
            with amnesia. Snorkel stores <b>raw samples</b> in <b>datasets</b>
            and dynamically slices and aggregates them in real time. As the
            samples age, they can be set to <b>automatically expire</b>, keeping
            query times snappy.
          </p>
  
        <h2>When do I sample data?</h2>
          <p>
            Typically, datasets tend to hold a few weeks worth of information. If
            you find that your samples are not sticking around for long enough,
            you should consider <b>sampling</b> the data down and adding a
            <b>weight</b> or <b>sample_rate</b> field that represents that
            sample's weight. Snorkel does the right thing and
            will account for the sample rate when doing its aggregations.
