Analysing Large Datasets Efficiently with Apache Spark and IntelliJ IDEASummit 2020

As a Data Engineer you're building the foundation for the success of any data-driven products or projects your company may envision. No pressure. And, of course, every time you write Spark code, everything runs flawlessly and blazingly fast on the first try, right? Sadly, that's not the case. From a typo in a method name to a non-optimal way of writing a job, numerous things could result in hours of work wasted - waiting for that Spark job to finish only to crash on the last line. It doesn't have to be that way. In this talk I'll show you how you can be more productive when writing Spark jobs to process data. We'll also look into monitoring and optimizing Spark jobs. All without leaving IntelliJ IDEA.
