Apache Spark has become one of the most used frameworks for distributed data processing. Its mature codebase, horizontal scalability, and resilience make it a great tool to process huge amounts of data.

Spark’s great power and flexibility requires a developer that does not only know the Spark API well: They must also know about the pitfalls of distributed storage, how to structure a data processing pipeline that has to handle the 5V of Big Data—volume, velocity, variety, veracity, and value—and how to turn that into maintainable code.
