Hector是否提供API來支持組合鍵？

Question

現在，我必須通過將子鍵一起格式化來手動生成組合鍵。這是醜陋的，沒有效率。我想知道Hector是否提供了這樣一組API以更體面的方式處理複合鍵。

是的，它的確如此。

你可以看一下DynamicCompositeTest的例子：

https://github.com/rantav/hector/blob/master/core/src/test/java/me/prettyprint/hector/api/beans/DynamicCompositeTest.java

@Test 
public void allTypesSerialize() { 
    DynamicComposite composite = new DynamicComposite(); 

    UUID lexUUID = UUID.randomUUID(); 
    com.eaio.uuid.UUID timeUUID = new com.eaio.uuid.UUID(); 


    //add all forward comparators 
    composite.addComponent(0, "AsciiText", AsciiSerializer.get(), "AsciiType", ComponentEquality.EQUAL); 
    composite.addComponent(1, new byte[]{0, 1, 2, 3}, BytesArraySerializer.get(), "BytesType", ComponentEquality.EQUAL); 
    composite.addComponent(2, -1, IntegerSerializer.get(), "IntegerType", ComponentEquality.EQUAL); 
    composite.addComponent(3, lexUUID, UUIDSerializer.get(), "LexicalUUIDType", ComponentEquality.EQUAL); 
    composite.addComponent(4, -1l, LongSerializer.get(), "LongType", ComponentEquality.EQUAL); 
    composite.addComponent(5, timeUUID, TimeUUIDSerializer.get(), "TimeUUIDType", ComponentEquality.EQUAL); 
    composite.addComponent(6, "UTF8Text", StringSerializer.get(), "UTF8Type", ComponentEquality.EQUAL); 
    composite.addComponent(7, lexUUID, UUIDSerializer.get(), "UUIDType", ComponentEquality.EQUAL);
