Subject [jira] Created: (CASSANDRA-2232) Clean up and document EstimatedHistogram
Date Wed, 23 Feb 2011 23:22:39 GMT
Clean up and document EstimatedHistogram

                 Key: CASSANDRA-2232
             Project: Cassandra
          Issue Type: Improvement
            Reporter: Jonathan Ellis
            Assignee: Jonathan Ellis
            Priority: Minor
             Fix For: 0.7.3

EstimatedHistogram treats adding value n as adding a value infinitesimally greater than n.
 This barely made sense for the original goal of latency tracking but is clearly broken for
inherently integral data like sstables-per-read.

Also, median() is broken, but even a non-broken median() would not be correct to use in mean
row size reporting which is its only caller.
