------------------------------
Summary: Add support for MapValues
Key: BEAM-611
URL: https://issues.apache.org/jira/browse/BEAM-611
Project: Beam
Issue Type: Improvement
Components: sdk-ideas
Reporter: Luke Cwik
Priority: Minor
Filed from: https://github.com/GoogleCloudPlatform/DataflowJavaSDK/issues/412
Often I find myself needing to simply map a function over just the values of a
key-valued PCollection. MapElements works for this, but suffers a small hit in
readability (imho) and introduces some possibility for error.
I wanted to see if there is any bandwidth / interest in adding this as a
standard transform to the SDK. If so, I have attached a gist with a basic spike
I have been using in my flows:
