As far as I know, this and KDB have very different use cases. KDB is a single box timeseries database - the closest open source analogue would probably be using Pandas + a big folder of CSV files. (KDB performs a lot better than this, however.)<p>The use case is storing tick data + economic data for all the symbols. I.e., one timeseries per publicly traded company. The primary use case is loading a significant chunk of that data and running some statistical analysis on it.<p>Also KDB pricing starts at $100k or something like that.<p>In contrast, Riak&#x27;s timeseries product is distributed. It could store millions of timeseries if you throw enough boxes at it. You probably won&#x27;t be loading all the data for analysis, probably you&#x27;ll be processing some of the data one series at a time, and the rest is just for reference.<p>The main use case here is sensor networks (aka &quot;internet of things&quot;) more than financial data. I.e., one timeseries <i>per rotor on a drone</i>, or per sensor on your phone, sometihng like that.
