Migrating from a plain Spark Application to ZIO with ZparkIO

In this article, we’ll see how you can migrate your Spark Application into ZIO and ZparkIO, so you can benefit from all the wonderful features that ZIO offers and that we’ll be discussing.

What is ZIO?

ZIO is defined, according to official documentation as a library for asynchronous and concurrent programming that is based on pure functional programming. In other words, ZIO helps us write code with type-safe, composable and easily testable code, all by using safe and side-effect-free code. ZIO is a data type. Its signature, ZIO[R, E, A] shows us that it has three parameters:

Scala is a hot language in software development today, it is used by a range of start-ups for application development and has been adopted as the unofficial language of big data software development thanks to frameworks like Spark. As a language it is less verbose than Java, and has a number of unique features that make it more flexible too. Scala is both functional, object oriented, and truly multi-threaded – so it provides a very unique development environment. There’s so much to Scala that whatever stage of programming you’re at, you’ll probably want some books!
