Apache Spark: broadcast joins

When to use

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

Procedure

Force/prevent broadcast joins with hints, set the broadcast threshold, and avoid shuffles when one side is small.

Notes

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