Subject [jira] [Created] (CASSANDRA-6667) Mean cells per sstable is calculated incorrectly
Date Thu, 06 Feb 2014 18:34:10 GMT
Jonathan Ellis created CASSANDRA-6667:
-----------------------------------------

             Summary: Mean cells per sstable is calculated incorrectly
                 Key: CASSANDRA-6667
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-6667
             Project: Cassandra
          Issue Type: Bug
            Reporter: Jonathan Ellis
            Priority: Minor


We currently take the average of the mean for each partition, rather than correctly weighting
by cell count.  This affects hint paging as well as index selectivity calculation.
