1. Optimization? Why? How? When? What? "Spark applications also need to be optimized. "Many people may have this question," not already have code generators, executive optimizer, pipeline or something. ”。 Yes, Spark does have some powerful built-in tools to make your code faster when it executes. But if everything depends on the tools, framework to do, I think that can only illustrate two questions: you a

Spark example: Sorting by array and spark example Array sorting is a common operation. The lower performance limit of a comparison-based sorting algorithm is O (nlog (n), but in a distributed environment, we can improve the performance. Here we show the implementation of array sorting in Spark, analyze the performance, and try to find the cause of performance imp
