Which is faster PySpark or Scala?
Scala and PySpark should perform relatively equally for DataFrame operations. This thread has a dated performance comparison. “Regular” Scala code can run 10-20x faster than “regular” Python code, but that PySpark isn’t executed liked like regular Python code, so this performance comparison isn’t relevant.
How tough is PySpark?
PySpark offers a very high level of abstraction over layers of complexity involved in distributed processing. It can be difficult to understand what is happening “underneath”.

What are the features of Scala 3?
Performance-oriented language features. While value classes continue to work, Scala 3 brings opaque type aliases that provide type abstraction without any overhead. Inline methods can be used for methods that are guaranteed to be inlined at compile-time. Scala 3 currently does not implement specialization.
