InfluxDB

InfluxDB was written in Google's new Go language and has been open sourced for easier and faster development.

The database engine itself has no external dependencies which allows it to be installed on most operating systems that can run Go.

The entire InfluxDB engine is a  distributed database, which in turn makes it scale up or down to any cluster size and installation type.

The main purpose behind the creation of InfluxDB was to provide a database that makes data available as soon as it indexes it (learns it).

This makes InfluxDB one of the few real-time databases around.
