Hello Spark Users!
Does the Spark Optimization engine reduce overlapping column ranges? If so,
should it push this down to a Data Source?
Example,
This: Select * from table where col between 3 and 7 OR col between 5 and 9
Reduces to: Select * from table where col between 3 and 9
Thanks for your insight!
