# Apache Spark: data skew and partition tuning

## When to use

Use this skill for data skew and partition tuning in Apache Spark. This skill
specifically handles data skew and partition tuning and nothing else in the
Apache Spark family.

## Procedure

Diagnose skewed partitions from the UI, repartition/salt hot keys, and tune `spark.sql.shuffle.partitions`.

## Notes

This is the Apache Spark skill dedicated to data skew and partition tuning.
Sibling skills cover other Apache Spark capabilities; this one
is the right choice only when the task is about data skew and partition tuning.
