I still don't completely grasp what this is. Is it actually a database application that is specifically built to scale-out (shard) time series data?

  In short no. In long, there have been attempts mostly failed ones. The current industry standard is making a big NAS and putting paths to log files in an SQL database, and make a nice java front end to chop up logs by time stamp. The idea is from a testing perspective (I do data acquisition and analysis for test systems), is when a part breaks, or something critical in your test happens. You want to find the source of failure. Often times analyzing every single data point is pointless, especially after a 10 hour test with 100 points per second per channel. And you only want to see ~2 minutes of data. How most systems work is you need to open up a measurement file, and either use a stand alone tool to chop this (and pray it doesn't corrupt your measurement file). Or from what I understand Influx simply lets you query time code to time code and return channels via pattern matching within that time span. Very simple. Data management is another big issue. A single day's worth of road test can be ~5-10TB per vehicle (2 months of testing + 20 vehicle fleet). Also this total is project to like all things double every year -_-' Also as far as I understand Influx doesn't support sound or video. Which is really what aerospace and automotive are looking for.

    The upcoming version will have support for raw byte values. Then you'll be able to query those out based on tagged metadata and the time. Custom processing against raw byte values (and other custom functions) should come sometime next year.
