<p>Druid was created by advertising analytics startup <a href="https://metamarkets.com/">Metamarkets</a> <em>(see disclosure)</em> and is <a href="http://druid.io/druid-powered.html">used by numerous large web companies</a>, including eBay, <a href="https://gigaom.com/2013/12/09/netflix-open-sources-its-data-traffic-cop-suro/">Netflix</a>, PayPal, Time Warner Cable and <a href="http://www.slideshare.net/ydn/pushing-thelimitsofrealtimeanalyticswithdruidv3">Yahoo</a>. Because of the nature Metamarkets&#8217; business, Druid requires data to include a timestamp and is probably best described as a time-series database. It&#8217;s designed to ingest terabytes of data per hour and is often used for things such as analyzing user or network activity over time.</p>
<p>Mike Driscoll, Metamarkets&#8217; co-founder and CEO, is confident now is the time for open source tools to really catch on &#8212; even more so than they already have in the form of Hadoop and various NoSQL data stores &#8212; because of the ubiquity of software as a service and the emergence of <a href="https://gigaom.com/2015/02/11/meet-myriad-a-new-project-for-running-hadoop-on-mesos/">new resource managers such as Apache Mesos</a>. In the former case, open source technologies underpin multiuser applications that require a high degree of scale and flexibility on the infrastructure level, while in the latter case databases like Druid are just delivered as a service internally from a company&#8217;s pool of resources.</p>
<p class="p1">However it happens, Driscoll said, &#8220;I don’t think proprietary databases have long for this world.&#8221;</p>
