SQL Performance Improvements at a Glance in Apache Spark 3.0Summit 2020

This talk explains how Spark 3.0 can improve the performance of SQL applications. Spark 3.0 provides many performance features such as dynamic partitioning and enhanced pushdown. Each of them can improve the performance of a different type of SQL application. Since the number of features is large, it is not easy for application developers to understand these features at a glance. This talk gives a brief explanation of these features with an example program and explains how it works and how we can improve the performance.

Here are takeaways of this talk:

  1. What optimization features for SQL Spark 3.0 support.
  2. Which programs Spark 3.0 can accelerate.
