Example: Simple EVCache

Below example depicts the use case for storing customer data in EVCache hosts (host1 and host2). The name of the EVCache cluster is called as EVCACHE_CUSTOMER and the cache name is called as cid.

Setting the Properties

Set the following properties before initializing EVCache or pass it as a command line argument -D

System.setProperty("EVCACHE_CUSTOMER.use.simple.node.list.provider", "true");
/*
Where host1 and host2 is the name of the host when memcached is running and port is the memcached port 
*/
System.setProperty("EVCACHE_CUSTOMER-NODES", "servergroup0=host01:port,host02:port;servergroup1=host11:port,host12:port;servergroup2=host21:port,host22:port,host23:port"); 

Initializing the pool (optional)

Optionally, you can initialize the EVCache Client Pool when your application/server is starting. This will establish the connection to an EVCache cluster called as EVCACHE_CUSTOMER

EVCacheClientPoolManager.getInstance().initEVCache("EVCACHE_CUSTOMER");

Creating EVCache instance

Create an instance of EVCache using the Builder passing the app name EVCACHE_CUSTOMER and the cache name called as cid. The cache name (optional) is used to prefix the keys stored in EVCache to avoid cache collisions.

EVCache evCache = (new EVCache.Builder()).setAppName("EVCACHE_CUSTOMER").setCacheName("cid").enableZoneFallback().build();

Performing operations on EVCache

//Sets the key: "Hello" to value: "World" for a time of 900 seconds in EVCache.
evCache.set("Hello", "World", 900);

//Gets the value for key: "Hello" from EVCache.
String value = evCache.get("Hello");

//Deletes the value for key: "Hello" from EVCache.
evCache.delete("Hello");
