      Description

      during flush and compaction we should keep row size statistics using EstimatedHistogram (column count, and row size), replacing min/max/total sizes in CFS.

      having this detail will let us estimate, given an index CF, how many nodes we need to query to get the number of matching rows requested by the client.
