Already been done in 2001-2004: Sensage (<a href="http://www.sensage.com/" rel="nofollow">http://www.sensage.com/</a>, <a href="http://en.wikipedia.org/wiki/Sensage" rel="nofollow">http://en.wikipedia.org/wiki/Sensage</a>), followed by Vertica, etc. All the columnar-storage big-table timestamped data collectors and data aggregators. Sensage failed at the market. Splunk succeeded, perhaps with a different underlying data storage model, but certainly with great marketing.<p>What's different about InfluxDB?
