> Currently adding multiple column range predicates for the same column does essentially an AND between the two predicates which will cause no results to be returned. 
> This would greatly increase performance were I can complete in one scan what would otherwise take two.
> As an example using the java api:
> ColumnRangePredicate columnRangePredicateColumnNameA = new ColumnRangePredicate(new ColumnSchema.ColumnSchemaBuilder("column_name", Type.STRING).build());
> columnRangePredicateColumnNameA.setLowerBound("A");
> columnRangePredicateColumnNameA.setUpperBound("A");
> ColumnRangePredicate columnRangePredicateColumnNameB = new ColumnRangePredicate(new ColumnSchema.ColumnSchemaBuilder("column_name", Type.STRING).build());
> columnRangePredicateColumnNameB.setLowerBound("B");
> columnRangePredicateColumnNameB.setUpperBound("B");
> which would be equivalent:
> select * from some_table where column_name="A" or column_name="B"
