Apache Spark Application Performance Tuning Course Overview

This hands-on training session consists of three days and is designed to provide developers with the core ideas and knowledge they need to boost the performance of their Apache Spark applications. The participants in the Apache Spark Application Performance Tuning Course

will learn how to identify typical reasons of poor performance in Spark applications, approaches for avoiding or correcting such problems, as well as best practices for monitoring Spark applications.

Target Audience:

This training is intended for software developers, engineers, and data scientists who are familiar with the process of developing Spark applications and are interested in enhancing the performance of their own code.

Learning Objective for Apache Spark Application Performance Tuning Course: 

  • Acquire an understanding of Apache Spark's architecture, job execution, and the ways in which efficiency at runtime may be improved using methods like as pipelining and lazy execution
  • Conduct an analysis of the operational parameters of fundamental data structures such as RDD and DataFrames.
  • Choose the document formats that will allow your program to function with the most efficiency.
  • Determine and correct the performance issues brought on by the skew in the data.
  • Improving SparkSQL speed may be accomplished via the use of partitioning, bucketing, and join improvements.
  • Gain an understanding of the performance impact that Python-based user-defined functions, RDDs, and DataFrames may have on your application.
  • Caching may help improve the speed of applications, so take use of it.
  • Gain an understanding of the operation of the Catalyst and Tungsten optimizers.
  • Gain an understanding of how Workload XM may assist in troubleshooting and proactively monitoring the performance of Spark applications.
  • Discover the new features that are available in Spark 3.0 and, in particular, how the Adaptive Query Execution engine makes speed improvements.
  • Due to the limited availability of this program, it may take up to three weeks to organize the necessary logistics.
