The term Scala originated from “Scalable language” and it means that Scala grows with you. In recent times, Scala has attracted developers because it has enabled them to deliver things faster with fewer codes. Developers are now much more interested in having Scala training to excel in the big data field.

It's always a huge pleasure to see the PySpark API covering more and more Scala API features. But since the API is a little bit different than the one available on the Scala side, I wanted to take a deeper look.
