Use Infinispan Memcached Server framework to achieve efficient distributed cache
Overview:
A distributed cache is a solution to solve the speed and scalability of data access.Infinispan is an open source distributed data grid solution, combining the characteristics of memory cache and distributed database.The Infinispan Memcached Server framework is a component in the INFINISPAN project. Based on the MEMCACHED protocol, a distributed cache service is achieved. It provides efficient data storage and access methods, suitable for large -scale distributed systems.
Functional characteristics:
1. Distributed data storage: Infinispan Memcached Server Framework distributed data on multiple physical nodes to achieve high availability and scalability of data.
2. Memory cache: Infinispan Memcached Server's framework to store data in memory, providing fast data access speed, suitable for storing high -frequency access data.
3. MEMCACHED protocol supports: Infinispan Memcached Server framework uses the Memcached protocol, which can be seamlessly integrated with the existing MEMCACHED client without changing the existing code.
4. persistent storage support: Infinispan Memcached Server framework supports the persistence of data to disk to ensure the reliability of data during node failure.
Example code:
Below is a sample code that uses the Infinispan Memcached Server framework to achieve a distributed cache.
First of all, we need to define an instance of a cache management class to initialize and manage the Infinispan Memcached Server framework:
import org.infinispan.server.memcached.MemcachedServer;
public class CacheManager {
private static MemcachedServer server;
public static void startCacheServer() {
server = new MemcachedServer();
server.start();
}
public static void stopCacheServer() {
server.stop();
}
}
Next, we can use the cache management class to start and close the INFINISPAN MEMCACACHED Server framework in the application.
public class MainApplication {
public static void main(String[] args) {
CacheManager.startCacheServer();
// Here you can perform cache -related operations
CacheManager.stopCacheServer();
}
}
We can then interact with INFINISPAN MEMCACACACHED Server framework using existing Memcached client code.For example, the following is an example code that uses Spymemcached client to access the cache:
import net.spy.memcached.MemcachedClient;
public class CacheClient {
private static final String CACHE_SERVER = "localhost";
private static final int CACHE_PORT = 11211;
public static void main(String[] args) {
try {
MemcachedClient memcachedClient = new MemcachedClient(new InetSocketAddress(CACHE_SERVER, CACHE_PORT));
// Store data to the cache
memcachedClient.set("key", 3600, "value");
// Obtain data from the cache
Object value = memcachedClient.get("key");
System.out.println("Value: " + value);
// Close the client connection
memcachedClient.shutdown();
} catch (Exception e) {
e.printStackTrace();
}
}
}
Here we use the SpyMemCached client to connect to the Infinispan Memcached Server framework and perform data storage and access operations.
in conclusion:
By using the Infinispan Memcached Server framework, we can achieve efficient distributed cache and improve data access speed and scalability.At the same time, by following the MEMCACHED protocol, we can seamlessly integrate with the existing Memcached client to reduce the cost of system transformation.In practical applications, configuration can be configured according to specific needs, such as setting the cache size, persistent storage method, etc. to meet the cache needs in different scenarios.
