Redis data types

After you have understood how Redis data types work, you will be able to design better applications and make better use of the available resources. It will also help you decide whether Redis is the right solution for your problem. The main reason for Redis to have many data types is very simple: one size does not fit all, and different problems require different solutions.

Although you do not need to use all the data types, it is important to understand how they work so that you can choose the right ones. By the end of this book, you will have a full understanding of these data types and know how to improve the performance of your applications using Redis.

Strings are the most versatile data types in Redis because they have many commands and multiple purposes. A String can behave as an integer, float, text string, or bitmap based on its value and the commands used. It can store any kind of data: text (XML, JSON, HTML, or raw text), integers, floats, or binary data (videos, images, or audio files). A String value cannot exceed 512 MB of text or binary data.
