Mastering High Performance with Kotlin

Overview of this book

The ease with which we write applications has been increasing, but with it comes the need to address their performance. A balancing act between easily implementing complex applications and keeping their performance optimal is a present-day requirement In this book, we explore how to achieve this crucial balance, while developing and deploying applications with Kotlin. The book starts by analyzing various Kotlin specifcations to identify those that have a potentially adverse effect on performance. Then, we move on to monitor techniques that enable us to identify performance bottlenecks and optimize performance metrics. Next, we look at techniques that help to us achieve high performance: memory optimization, concurrency, multi threading, scaling, and caching. We also look at fault tolerance solutions and the importance of logging. We'll also cover best practices of Kotlin programming that will help you to improve the quality of your code base. By the end of the book, you will have gained some insight into various techniques and solutions that will help to create high-performance applications in the Kotlin environment

Properties

To write code with minimum overhead, you first have to understand the difference between fields and properties. A field is just a variable of the class that holds a value. A property of the class includes the field, getter, and setter. Since Kotlin uses the concept of properties, you should know how to access a field directly without invoking the getter or setter.

Backing properties

If you need to access a field of a property inside a class in which it's declared, you can use backing properties. If you only need to access a field from the getter or setter of its property, it's enough to use backing fields. However, if you want to access a field somewhere else, you should use backing properties. Let&apos...
