I am wondering how close ticket #1072 is to implementation [1] We are about to do a proof of concept with cassandra to replace around 20 MySQL partitions (1 partition = 4 machines: master/slave in DC A, master/slave in DC B). We're essentially just counting web hits - around 10k/second at peak times - so increment counters is pretty much essential functionality for us. How close is the patch in #1072 to being acceptable? What is blocking it? Thanks, R. [1] https://issues.apache.org/jira/browse/CASSANDRA-1072
