I don&#x27;t know Riak, other than its a distributed NoSQL key-value data store.<p>Time series has always been prevalent in the fintec and quantitative finance, and other disciplines for decades. I read a book in the early 1990s on music as time series data, financial tickers, and so on.<p>How is Riak different, or more suited to use than  Kdb + q, J with JDB (free), Jd (a commercial J database like Kdb&#x2F;q)[2], or the new Kerf lang&#x2F;db being developed by Kevin Lawler[3]?<p>Kevin also wrote kona, an opensource version of the &quot;K programming language&quot;[4].<p>Kdb is very fast at time series analysis on large datasets, and has many years of proven value in the financial industry.<p>[1]  <a href="https:&#x2F;&#x2F;kx.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;kx.com&#x2F;</a>
