Takes a keyed collection of elements and produces a collection
where each element consists of a key and all values associated with that key.
See more information in the [Beam Programming Guide](/documentation/programming-guide/#groupbykey).
## Examples
-See [BEAM-7390](https://issues.apache.org/jira/browse/BEAM-7390) for updates.
-## Related transforms
+In the following example, we create a pipeline with a `PCollection` of produce keyed by season.
+
+We use `GroupByKey` group all the produce for each season.
Review comment:
Missing a "to"
We use `GroupByKey` *to* group all the produce for each season.
