Performance optimization is to improve the system performance, reduce energy usage, or reduce the impact of applications on other parts. If the optimization is hasty or there is no measurement, of course, performance optimization may have a bad effect.
Performance optimization is to improve the system

ObjectiveIn the field of big data computing, Spark has become one of the increasingly popular and increasingly popular computing platforms. Spark's capabilities include offline batch processing in big data, SQL class processing, streaming/real-time computing, machine learning, graph computing, and many different types of computing operations, with a wide range of applications and prospects. In the mass reviews, many students have tried to use spark in various projects. Most students, including t

Does the actual load exceed the system's load capacity? is the system not optimized?Through these analysis and some system-related problems, the system bottleneck can be more in-depth understanding, and then analyze the real cause.
