Description
There are three different tunable settings available for memtable sizing. Tuning these is an important task to operations centric people, because it relates to JVM memory management. Currently, the code logs when you have hit one of the three thresholds, but it does not tell you which of the three you have hit.
Attached patches against 0.6 and 0.7 branches add a log message for each of the thresholds, indicating which one has been reached. If you were to find yourself in the somewhat unlikely case of simultaneously hitting more than one, the new code would only tell you which one you hit first, because that's all the current codepath cares about.
