Use Infinispan Memcached Server framework to build scalable memory databases
Introduction:
Memory database is a high -performance, low -delay database type, which can store data in memory to speed up data access.INFINISPAN MEMCACACHED Server framework is an open source memory database solution. It is based on Java development and provides rich functions and flexible scalability.This article will introduce how to use the Infinispan Memcached Server framework to construct a scalable memory database and provide some Java code examples.
Step 1: Installation and configuration Infinispan Memcached Server framework
First, we need to install and configure the Infinispan Memcached Server framework.You can download the latest framework package from Infinispan's official website and decompress it to the specified directory.Then, according to the document of the framework, the configuration server is configured to enable the MEMCACHED protocol and other required configuration parameters.
Step 2: Create and configure Infinispan cache
After completing the installation and configuration of the framework, we need to create and configure the INFINISPAN cache.You can understand how to create a basic Infinispan cache through the following example examples:
import org.infinispan.client.hotrod.Configuration;
import org.infinispan.client.hotrod.RemoteCache;
import org.infinispan.client.hotrod.RemoteCacheManager;
public class InfinispanCacheExample {
public static void main(String[] args) {
Configuration configuration = new ConfigurationBuilder().addServer().host("localhost").port(11222).build();
RemoteCacheManager cacheManager = new RemoteCacheManager(configuration);
RemoteCache<String, String> cache = cacheManager.getCache("myCache");
cache.put("key1", "value1");
String value = cache.get("key1");
System.out.println("Retrieved value: " + value);
}
}
The above code creates an INFINISPAN remote cache manager and obtained a cache instance called "MyCache" from it.We can use the "PUT" method to store the key value into the cache and use the "GET" method to check the value from the cache.
Step 3: Extend the Infinispan cache
INFINISPAN MEMCACACHED Server framework supports the construction of scalable memory databases through horizontal expansion.We can increase the capacity and performance of the system by adding more server nodes.The following is a sample code for the expansion of Infinispan cache:
import org.infinispan.client.hotrod.Configuration;
import org.infinispan.client.hotrod.RemoteCache;
import org.infinispan.client.hotrod.RemoteCacheManager;
public class InfinispanCacheExample {
public static void main(String[] args) {
Configuration configuration = new ConfigurationBuilder().addServers("localhost:11222", "localhost:11223").build();
RemoteCacheManager cacheManager = new RemoteCacheManager(configuration);
RemoteCache<String, String> cache = cacheManager.getCache("myCache");
cache.put("key1", "value1");
String value = cache.get("key1");
System.out.println("Retrieved value: " + value);
}
}
The above code modified the configuration to connect it to two different server nodes.Adding a new server node will share more loads and increase the capacity of the system.
in conclusion:
Through INFINISPAN MEMCACACHED Server, we can easily build scalable memory databases.This article introduces the basic steps to create and configure the Infinispan cache using the framework, and provide some Java code examples.Through horizontal expansion server nodes, we can increase the capacity and performance of the system.This makes INFINISPAN MEMCACACHED Server an ideal choice for building a high -performance memory database.
Please note that the above code examples are only used to demonstrate the purpose. In actual use, you may need to be modified and customized according to specific needs.
