research at the same time. As a discipline, data science covers a broad range of areas: data engineering, data analysis, machine learning, visualization, and many more. To cover all these di�erent areas support for the Apache Spark cluster computing system, which is particularly useful for data engineering. Spark provides a high-level API in multiple languages. The language support in Zeppelin is provided Zeppelin interpreter Setting up Zeppelin with Kotlin interpreter — — — — 16 For software engineering, an important part of any domain is the availability of frameworks for related areas.
