Built-in functions

We have a modest library of built-in functions. Feel free to contribute your own.

Storage Functions

These functions are used for loading/storing data.

Filter Functions

Eval Functions

Group Functions

There are as yet no built-in group functions because usually users just want to group by the values of fields. If you want all tuples to go in the same group, you can use GROUP <alias> ALL. Similarly, you can say GROUP <alias> ANY if you don't care about how tuples are grouped. See PigLatin.
