Smart grid with time series and tick database Kerf (getkerf.wordpress.com)

Kerf looks to be a more readable contender in the KDB+/Q market of time series, columnar, in memory databases with built-in language. IOT, will and already is providing, all sorts of real time data that grows in value the faster and more analytically it can be dealt with. From the examples I've seen online, I like the syntax. It seems to strike a good balance between concise, and powerful pre-defined analytic functions.
