      Description

      There were several deficiencies introduced with TEIID-4332 -

      In some circumstances very low ndv values on the large side of a join would cause a dependent join in an unexpected direction.

      The row estimate derived for a join without ndv information would tend to be too low, which would have a cumulative effect through further joins.
