Why Scala is preferred for Spark?
Developers state that using Scala helps dig deep into Spark’s source code so that they can easily access and implement the newest features of Spark. Scala’s interoperability with Java is its biggest attraction as java developers can easily get on the learning path by grasping the object oriented concepts quickly.
Why Scala is better than Python?
When it comes to performance, Scala is almost ten times faster than Python. Scala’s reliance on the Java Virtual Machine (JVM) during runtime imparts speed to it. Generally, compiled languages perform faster than interpreted languages. Since Python is dynamically typed, the development speed reduces.
