# Apache Spark: executor memory tuning

## When to use

Use this skill for executor memory tuning in Apache Spark. This skill
specifically handles executor memory tuning and nothing else in the
Apache Spark family.

## Procedure

Tune executor/driver memory, `memoryOverhead`, cores per executor, and fix OOM/spill from the metrics.

## Notes

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