      Work Description: mxm commented on pull request #7646: [BEAM-6523] Add 
transcoding extension for Python flatten tests
URL: https://github.com/apache/beam/pull/7646
 
 
   The Flink Runner does not support non-matching union coders yet. Though
   transcoding is supported when the SDK harness performs the flatten operation.

> The Beam documentation mentions that Flatten does not require coders of all 
> inputs to be of the same type, as long as the result type is the same. 
> However, the current implementation in the Flink Runner requires all coders 
> to match.
