> Add MapValues and MapKeys functions
> -----------------------------------
>
> Key: BEAM-621
> URL: https://issues.apache.org/jira/browse/BEAM-621
> Project: Beam
> Issue Type: New Feature
> Components: sdk-java-core, sdk-py-core
> Reporter: Jean-Baptiste Onofré
> Assignee: Vitaly Terentyev
> Priority: P3
> Labels: Clarified, newbie, starter
> Time Spent: 2h 20m
> Remaining Estimate: 0h
>
> Currently, we have the {{MapElements}} {{PTransform}} that "convert" a
> {{PCollection}} of {{KV}} to another {{PCollection}} (for instance
> {{String}}).
> A very classic mapping function is to just have the keys or values of {{KV}}.
> To do it currently, we can use {{MapElements}} or a generic {{ParDo}} (with
> {{DoFn}}).
> It would be helpful and reduce the user code to have {{MapValues}} and
> {{MapKeys}}. It would take a {{PCollection}} of {{KV}}: {{MapKeys}} will map
> the input {{PCollection}} to a {{PCollection}} of {{K}} and {{MapValues}} to
> a {{PCollection}} of {{V}}.
