# Apache Spark: checkpointing and lineage truncation

## When to use

Use this skill for checkpointing and lineage truncation in Apache Spark. This skill
specifically handles checkpointing and lineage truncation and nothing else in the
Apache Spark family.

## Procedure

Use `checkpoint()` to truncate long lineage in iterative jobs, configure the checkpoint dir, and balance cost vs recompute.

## Notes

This is the Apache Spark skill dedicated to checkpointing and lineage truncation.
Sibling skills cover other Apache Spark capabilities; this one
is the right choice only when the task is about checkpointing and lineage truncation.
