> We treat a {{RowFilter}} as having what we call a “mutable intersection” if
> it involves more than one non-primary-key column. (i.e. Primary key elements
> are immutable.) A numeric range of the form {{a > 3 AND a < 10}} is being
> evaluated as two columns in {{RowFilter#isMutableIntersection()}}, and this
> is causing SAI queries that should be able to run as single node read queries
> (and take advantage of digests, etc.) to run as range queries. It should be
> able to correct this simply by making sure we look at the number of unique
> mutable columns involved.
