2. Characteristics of Scala

Elegance: this is the first question for framework designers to consider. The users of the framework are application development programmers. The elegance of API directly affects the user experience.

Speed: Scala language has strong expressive ability, one line of code is worth multiple lines of Java, and the development speed is fast. Scala is statically compiled, so it is much faster than JRuby,Groovy.

Can integrate into the Hadoop ecosystem: Hadoop is now the de facto standard of big data. The emergence of Spark is not to replace Hadoop, but to improve the Hadoop ecology. Most JVM languages may think of Java, but the API made by Java is too ugly, or it takes too much effort to implement an elegant API.

3. Activity degree

As the source programming language of Spark, the popular open source big data memory computing engine, Spark has good performance advantages.

Scala will become the mainstream language processed by big data in the future.
