Why should we use distinct keyword in pig script

0 votes

Hi,

I am new to Apache Pig and started working with the fundamentals. There I came through a keyword "Distinct" but did not understand why to use it. Can anyone tell the use of this keyword?

Hey,

The "distinct" statement is very simple. It removes duplicate records. It works only on entire records, not on individual fields.
