Overview of this book

As applications built on the Salesforce platform are now a key part of many organizations, developers are shifting focus to Apex, Salesforce’s proprietary programming language. As a Salesforce developer, it is important to understand the range of tools at your disposal, how and when to use them, and best practices for working with Apex. Mastering Apex Programming will help you explore the advanced features of Apex programming and guide you in delivering robust solutions that scale. This book starts by taking you through common Apex mistakes, debugging, exception handling, and testing. You'll then discover different asynchronous Apex programming options and develop custom Apex REST web services. The book shows you how to define and utilize Batch Apex, Queueable Apex, and Scheduled Apex using common scenarios before teaching you how to define, publish, and consume platform events and RESTful endpoints with Apex. Finally, you'll learn how to profile and improve the performance of your Apex application, including architecture trade-offs. With code examples used to facilitate discussion throughout, by the end of the book, you'll have developed the skills needed to build robust and scalable applications in Apex.

Chapter 15: Improving Apex Performance

In the previous chapters of this section, we have focused on the practices involved in profiling the performance of our application to ensure that we can take measurements that will allow us to correctly analyze the performance of the system, as well as how to undertake that analysis.

In this chapter, we are going to focus on practical ways in which you can improve the performance of your code. This list is not a comprehensive list of every possible performance optimization you can make, but rather is a set of optimizations that can help in most instances without being specific to the exact underlying code. Again, performance will be dictated by what your code needs to do, so some of these methods may not apply, but as general patterns and principles, they should assist in improving your code performance overall.

In this chapter, we will cover the following topics:

  • Improving CPU time
  • Heap size
  • Query selectivity
  • Number...
