Abstract
This study conducts an in-depth exploration of performance optimization for the Spark-based big data processing fr amework. With the advent of the big data era, Spark, as a mainstream big data processing engine, has a direct impact on data processing efficiency and quality through its performance. The aim of this research is to uncover key techniques and methods for Spark performance optimization through systematic analysis and experimental verification. In this study, we employ a combination of quantitative analysis and qualitative evaluation. Initially, we analyze the performance bottlenecks during Spark job execution. Subsequently, we propose a series of targeted optimization strategies, including memory management optimization, task scheduling improvements, and data skew handling mechanisms. Through experimental comparisons, we find that the optimized Spark fr amework achieves significant improvements in data processing speed, resource utilization, and system stability. This study not only provides theoretical support and practical guidance for Spark performance optimization but also makes a positive contribution to technological advancements in the field of big data processing. Through the innovative practices of this research, we hope to promote the wider application and deeper development of big data processing technology.
