> -----------------------------
>
> Key: CRUNCH-3
> URL: https://issues.apache.org/jira/browse/CRUNCH-3
> Project: Crunch
> Issue Type: New Feature
> Components: MapReduce Patterns
> Reporter: Josh Wills
> Assignee: Gabriel Reid
>
> Replicated joins are a common way to improve performance when joining a large
> dataset with a small one. The smaller dataset is loaded into memory in the
> mapper/reducer tasks, and is then joined with the larger dataset as the large
> one is processed by the MapReduce job itself.
