Spring boot redis cache tutorial

When developing applications with Spring Bootone has to consider an important aspect that arises with the usage of persistent, non-in-memory databases such as PostgreSQL: performance.

Many a time, we all come to a phase when our application does not perform well as it is expected to. Apart from several other solutions, we also look for a caching technique to make DB calls faster. In order to make it possible, we have Redis Cache technique in place. Redis cache helps us by minimizing the number of network calls while accessing the data from DB. Moreover, apart from Cache, Redis can also be used as a database and Message Broker. Redis is an open source BSD licensed in-memory remote data structure store database that offers high performance, replication, and a unique data model.

As a junior developer, you've likely heard about Redis and Spring Boot, two powerful technologies that can supercharge your applications. Redis is an in-memory data store known for its speed and versatility, while Spring Boot simplifies Java application development. We'll also delve into the various types of values you can store in Redis and the use cases for each. Before we dive into Redis and Spring Boot integration, make sure you have the following tools and knowledge:. If you're new to Spring Boot, consider going through some introductory tutorials first. Maven or Gradle: A basic understanding of build tools like Maven or Gradle is helpful for managing dependencies. Redis: Install and configure a Redis server on your local machine or use a cloud-based Redis service. You can find installation instructions for Redis on the official website. Spring Boot: Have a Spring Boot application set up. If you don't have one, you can quickly generate a Spring Boot project using Spring Initializr. To use Redis as a caching mechanism in your Spring Boot application, you need to include the Spring Data Redis library as a dependency in your project. If you're using Maven, add the following dependency to your pom. Next, configure your Redis connection in application.

Sets : Store unique, unordered values.

.

When a service experiences a high volume of requests and the requested data remains static, a caching solution can significantly reduce response times and lighten the load on the service. Cache is a type of auxiliary memory that is specifically designed to hold data and instructions that are frequently accessed by applications or websites. Its fast and easy accessibility makes it a valuable tool in helping these applications and websites work faster. For more details, please visit: What is a Cache? That means, the response for following queries will be cached:. What we need is to add config package and a service for caching abstraction.

In this tutorial, we will be discussing the integration of Redis cache with Spring Boot by developing a CRUD operation example using Jedis and spring boot starter data redis. In the tutorial, we will explore 2 different ways to perform CRUD operations. First, we will be defining our custom RedisTemplate and use HashOperations to perform get and put operations on Redis server. Next, we will be using Cacheable annotation to enable implicit caching mechanism by Spring Boot and upon cache miss, the lookup will be done in the DB with spring boot starter data jpa. Redis is an in-memory data structure store implementing a distributed, in-memory key-value database with optional durability. It can be used as a database, cache or as a message broker. Redis supports different kinds of abstract data structures, such as strings, lists, maps, sets, sorted sets, HyperLogLogs, bitmaps, streams, and spatial indexes.

Redis Cache is nothing but a Cache Management feature offered by Redis. This allows you to issue appropriate cache configurations depending on the data you want to cache and how often it needs to be updated or accessed. Geospatial Data : Store and query geographical information, such as locations of restaurants or points of interest. Search or use up and down arrow keys to select an item. The Redis Cache offers various features like how long you want to keep data, and which data to remove first, and some other bright caching models. Moreover, apart from Cache, Redis can also be used as a database and Message Broker. Similarly, we expect from you to further extend these examples and implement them in your project accordingly. Use cases include tracking tags, followers, and likes. WangGithub0 - Dec 8 ' Not great! Happy coding! T Model. Cacheable ; import org. The full form of Redis is Remote Directory Server. In addition, If there is any update in the future, we will also update the article accordingly.

Caching is the process of storing frequently accessed data to serve them quickly when needed. It reduces the response time of service and a load of requests to handle by a service. You need a caching solution when your service receives many requests and the data requested doesn't change much.

Integrating Redis with Spring Boot To use Redis as a caching mechanism in your Spring Boot application, you need to include the Spring Data Redis library as a dependency in your project. Similarly, if we have annotations of different type, we can group them using Caching annotation for better readability. The full form of Redis is Remote Directory Server. The above example was pretty simplistic: there was only one instance of our Spring Boot application running. Moreover, we can also apply a condition in the annotation by using the condition attribute. T Model. We apply it on the methods that get retrieve data from DB. Bruno Barbosa - Nov 7 ' However, we should not apply Cache feature in a Create operation as we will not get any benefit of it. They are as below:. The Cacheable annotation offers us to use attributes. More importantly, it offers significantly more data transfers per second. Sorted Sets : Similar to sets but with an associated score. Cacheable requires a return value of the method that adds or updates data in the cache. In a Spring Boot application, caching is typically managed using the Cacheable annotation.
