Learn about Infinispan caching technology

Infinispan is a highly integrated and flexible distributed memory object caching technology that provides advanced caching and data grid capabilities. As an advanced technology developed based on Java, Infinispan has many advantages and features. Its advantages, application scenarios and usage methods will be introduced in detail below.

1. Advantages of Infinispan

1. High availability and fault tolerance

Infinispan is based on a distributed architecture and can achieve high availability and fault tolerance. When a node fails, other nodes can automatically take over, ensuring system continuity and availability.

2. High performance

Infinispan's performance is very efficient and it can cache various objects, including data in different formats such as Java serialized objects, POJO, JSON and XML. In addition, it also provides various caching strategies and data persistence methods to make data reading and writing speed more efficient.

3. Flexibility

Infinispan provides many configuration options to flexibly adjust cache functions and performance parameters according to application scenarios. At the same time, it also supports different distribution models and cluster configurations, such as peer nodes and master-slave nodes.

4. Easy to integrate

Infinispan has good scalability and ease of use, can be easily integrated into various Java applications, and is popular with Spring, Hibernate, JPA, etc. Framework integration.

2. Application scenarios of Infinispan

1. Cache

Infinispan can be used as a cache. By caching data, it can reduce the pressure on data storage and improve system throughput. and response speed.

2. Distributed lock

Distributed lock can be used to solve the mutual exclusion problem. Infinispan provides a distributed lock framework that can realize the function of distributed lock.

3. Distributed data storage

Infinispan can also be used as a distributed data storage, which can store data on multiple nodes to improve data availability and fault tolerance.

4. Distributed computing framework

Infinispan also provides a distributed computing framework, which can realize the processing and calculation of distributed tasks and make more efficient use of cluster resources.

3. How to use Infinispan

1. Dependency configuration

Add Infinispan dependencies through Maven or Gradle:

Maven:

<dependency>
    <groupId>org.infinispan</groupId>
    <artifactId>infinispan-core</artifactId>
    <version>11.0.7.Final</version>
</dependency>

Gradle:

implementation 'org.infinispan:infinispan-core:11.0.7.Final'

2. Set the configuration file

Infinispan uses XML or Properties files to set configuration information. Create a file named infinispan.xml or infinispan.properties on the classpath.

3. Create cache

To create an Infinispan cache in an application, you can create a cache by using the DefaultCacheManager class:

DefaultCacheManager cacheManager = new DefaultCacheManager("infinispan.xml");
Cache<String, Object> cache = cacheManager.getCache("myCache");

4. Use cache

You can use the put and get methods to write and read data from the cache:

cache.put("key1", "value1");
cache.put("key2", "value2");
Object value1 = cache.get("key1");
Object value2 = cache.get("key2");

5. Close the cache manager

Call the cacheManager.close() method to close the cache when the application is closed. Manager:

cacheManager.close();

Infinispan is a powerful caching technology that has the advantages of high availability, high performance, flexibility and easy integration, and can be applied to cache, distributed locks, distributed data storage and distributed computing frameworks and other fields. Through the above introduction, I believe you have understood the basic features and usage of Infinispan, and I hope it will be helpful to you.
