What is Scala
Scala is used in Big Data Processing, Machine Learning, Streaming Services, etc. It is designed to run big data applications based on Java. If your application requires big data processing which contains logs of SQL-like quries, and those query results needs some further processing according to some business logic implementations, it works for you.
With regard to Big Data Processing, check spark v.s. flink for details.
