Spring Boot + Redis + Docker: Ultimate Guide to Caching in Java
By Ayush Shrivastava · Updated Wed Apr 09 2025With Redis, your Spring Boot app can become faster and handle more traffic without breaking a sweat. This article will show you how to set it up step by step. However, before diving deep into Redis, we need to understand the concept of caching.
Cache is a fast, small, temporary storage frequently used by the computer or application to store and access important data.
It stores data in a key-value format. By leveraging cache memory, we can minimize database calls, improving application performance since database queries are typically resource-intensive.

The main objective of a cache is to speed up the retrieval of data by making a copy of the data in a location that can be accessed faster than the source or database.
