# Apache Spark: DataFrame transformations

## When to use

Use this skill for DataFrame transformations in Apache Spark. This skill
specifically handles DataFrame transformations and nothing else in the
Apache Spark family.

## Procedure

Build DataFrame pipelines with select/withColumn/groupBy, use built-in functions over UDFs, and chain transformations lazily.

## Notes

This is the Apache Spark skill dedicated to DataFrame transformations.
Sibling skills cover other Apache Spark capabilities; this one
is the right choice only when the task is about DataFrame transformations.
