riak-java-client 介绍
riak-java-client 是 Riak 的 Java 客户端开发类库，示例代码：

// add data to the bucket
myBucket.store("key1", "value1").execute();
//fetch it back
IRiakObject myData = myBucket.fetch("key1").execute();
// you can specify extra parameters to the store operation using the
// fluent builder style API

// delete
myBucket.delete("key1").rw(3).execute();
