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.
