Jonathan Ellis resolved CASSANDRA-5479. --------------------------------------- Resolution: Won't Fix Already noted as a feature request for CASSANDRA-4775. > hyper log log (hyperloglog) probabilistic counters > -------------------------------------------------- > > Key: CASSANDRA-5479 > URL: https://issues.apache.org/jira/browse/CASSANDRA-5479 > Project: Cassandra > Issue Type: Wish > Reporter: Nikolay > Priority: Minor > > Would be nice if we can include probabilistic counters in Cassandra. > People do not use them because people do not know their power. > HyperLogLog also can merge counters, so in case of node disconnections, > will be easy to have different versions on each node. When node come online, > it just merge the data from other nodes. > Same can be used when adding data - similarly to Counter_CF, > HyperLogLog will need to read single replica and add there. > Adding can be even add without reading - just drop the new "item" somewhere, > but then reading will be much more slow. -- This message is automatically generated by JIRA.
