---------------------------------
Summary: Allow runner to configure customization WindowedValue
coder such as ValueOnlyWindowedValueCoder
Key: BEAM-7951
URL: https://issues.apache.org/jira/browse/BEAM-7951
Project: Beam
Issue Type: Sub-task
Components: java-fn-execution
Reporter: sunjincheng
Fix For: 2.15.0
The coder of WindowedValue cannot be configured and it’s always
FullWindowedValueCoder. We don't need to serialize the timestamp, window and
pane properties in Flink and so it will be better to make the coder
configurable (i.e. allowing to use ValueOnlyWindowedValueCoder)
