Memcached (ix) client Advanced-java

Brief introduction

There are currently 3 Java clients in common use.

Memcachedclient

Spymemcached

Xmemcached

Memcachedclient: The author of the test, in high concurrency, easy to report abnormal, out of the Memory.

Spy: Performance is slightly worse than xmemcached.

Xmemcached: Although it is domestic, but preferred, performance and stability is very strong.

Xmemcached

Code resolution

Setting connection pooling and weights

Java code

Memcachedclientbuilder builder = new Xmemcachedclientbuilder (addrutil.getaddresses ("10.11.155.26:11211 10.11.155.41:11211 10.10.76.31:11211 10.10.76.35:11211 "), new int[] {1, 1, 1, 1});  
Set the connection pool size, that is, the number of clients     
builder.setconnectionpoolsize (50);

Name space

Java code

Memcachedclient.beginwithnamespace ("SX"); Name space

Set up a consistent hash algorithm and Failuremode

Java code

try {  
    Memcachedclientbuilder builder = new Xmemcachedclientbuilder (Addrutil.getaddressmap (" 10.10.160.153:11211,10.10.160.153:11212 "));  
      
    Builder.setsessionlocator (New Ketamamemcachedsessionlocator ());  
    Builder.setfailuremode (TRUE); In this mode, when a node is hung, requests to this node will throw the memcachedexception exception directly.   
    memcachedclient client = Builder.build ();  
} catch (Exception e) {  
    System.out.println ("Custom Exception");  
    E.printstacktrace ();  
}

Add a status Listener

Java code

Memcachedclient.addstatelistener (New Memcachedclientstatelistener ())//Here is an anonymous class

Integration with the spring3.2.5
