Trident中的解析包含的函数操作与投影操作

一：函数操作

1.介绍

　　Tuple本身是不可变的

　　Function只是在原有的基础上追加新的tuple

2.说明

　　如果原来的字段是log，flag

　　新增之后的tuple可以访问这些字段，log,flag,orderId,orderAmt,memberId

3.先写驱动类

　　增加了解析

　　然后再将解析的日志进行打印

二：投影操作

1.说明

　　可以对tuple进行裁剪操作。

2.驱动类

　　先投影

　　然后打印

三：解析

1.说明

　　这个部分在解析之后，进入分流阶段。涉及到全局分流与局部分流，现在先使用全局分流，进行打印验证。

2.聚合操作

　　部分删除，部分增加
