      Description

      We start of using Cube dataset or CDAP Metrics (powered by Cube) with FactTables having single region. This means all writes & queries hit same region and same RS. This is very non-optimal.

      The row key format in FactTables has aggregation group in the beginning - this allows to at least compute splits each per aggregation group
