Let’s look into the Apache pig architecture which is built on top of theHadoop ecosystemand uses a high-level data processing platform. Pig uses pig Latin data flow language which consists of relations and statements. Pig has a rich set of operators and data types to execute data flow in...
language, Pig Latin, for expressing these data flows. Pig Latin includes operators for many of the traditional data operations (join, sort, filter, etc.), as well as the ability for users to develop their own functions for reading, processing, and writing data. ...
布尔操作符(Boolean Operators)包括:AND、OR、IN、NOT。 类型转换操作符(Cast Operators):使用圆括号包含类型名,作用于一个字段,例如(int)age、(map[])、(chararray)COUNT($2)、(tuple(chararray,int,map[]))name_age_scores等等。 比较操作符(Comparison Operators)包括:==、!=、<、>、<=、>=、matches。
Apache Pig简介与实践 Apache Pig是一个用来分析大数据集的平台，它由两部分组成：一部分是用于表达数据分析程序的高级脚本语言，另一部分是用于评估分析程序的基本工具。目前来看，Pig主要用于离线数据的批量处理应用场景，但是随着Pig的发展处理数据的速度会不断地提升，这可能依赖于Pig底层的执行引擎。比如，Pig通过指定...
