Presentation:
Memory Management in Apache Spark

Spark and other modern analytics platforms are based on an in-memory computing model. Thus, it is no surprise that making effective use of memory is key to good performance of Spark jobs. But how does Spark use memory? And what can be done to use it more effectively? In this talk I’ll give an overview of memory usage in Spark, identify some memory management challenges, and consider how they might be addressed. This talk is based on joint work with Michael Mior.
