What is the purpose of the GROUPBY statement in Pig?

In Pig, the GROUP BY statement is used to group data based on a specified field. This allows records with the same value to be aggregated together and perform operations such as counting, summing, averaging, etc. GROUP BY is typically used in conjunction with aggregate functions like SUM, COUNT, AVG, to perform statistical and analytical operations on the grouped data. This statement in Pig enables similar functionality to the GROUP BY in SQL, allowing for grouping and summarizing operations on data.
