“I found Spark and I was really excited because I’m a functional programming nerd, and it was written in Scala.”

Apache Spark has skyrocketed in popularity lately, arguably surpassing Hadoop as the hottest big data technology as of late. Even IBM has thrown its weight behind the framework, calling it the “most important new open source project in a decade”. In this episode, Holden joins Software Engineering Daily to discuss why Spark is growing in popularity and how developers can begin learning the framework.

Holden Karau is a principal engineer at IBM working with Apache Spark. She is also an author of Learning Spark, a technical guide for developers new to the data processing framework.
