HyperLogLog implementation with Spark batch + Cassandra
<p>I am looking to implement HyperLogLog algorithm to count distinct users for different audience segments (or filters). I user Cassandra + Spark batch. Wondering if Cassandra provides any support for HyperLogLog type. </p>

<p>I could not find any plugin or anything related except <a href="http://vilkeliskis.com/blog/2013/12/28/hacking_cassandra.html" rel="nofollow noreferrer">http://vilkeliskis.com/blog/2013/12/28/hacking_cassandra.html</a> which is a great attempt but unfinished. </p>

<p>Thanks for any possible hints!</p>
