• Standard Hash, hash(key) mod server_count (余数分布)

  MemcachedClientBuilder builder = new XMemcachedClientBuilder(
					AddrUtil.getAddresses("server1:11211 server2:11211 server3:11211"));
  MemcachedClient mc = builder.build();

• Consistent Hash(一致性哈希)

  MemcachedClientBuilder builder = new XMemcachedClientBuilder(
					AddrUtil.getAddresses("server1:11211 server2:11211 server3:11211"));
  builder.setSessionLocator(new KetamaMemcachedSessionLocator());
  MemcachedClient mc = builder.build();

• Election Hash(选举散列)

   MemcachedClientBuilder builder = new XMemcachedClientBuilder(
					AddrUtil.getAddresses("server1:11211 server2:11211 server3:11211"));
  builder.setSessionLocator(new ElectionMemcachedSessionLocator());
  MemcachedClient mc = builder.build();
