- Pig Latin statements are the basic constructs you use to process data using Pig. A Pig Latin statement is an operator that takes a relation as input and produces another relation as output. (This definition applies to all Pig Latin operators except LOAD and STORE which read data from and write data to the file system.) Pig Latin statements may include expressions and schemas. Pig Latin statements can span multiple lines and must end with a semi-colon (). By default, Pig Latin statements are processed using multi-q[uery execution.
Pig Latin statements are generally organized as follows:
- A LOAD statement to read data from the file system.
- A series of "transformation" statements to process the data.
- A DUMP statement to view results or a STORE statement to save the results.
