[jira] [Commented] (BEAM-7951) Allow runner to configure customization WindowedValue coder such as ValueOnlyWindowedValueCoder

    [ https://issues.apache.org/jira/browse/BEAM-7951?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16958097#comment-16958097 ] 

Kenneth Knowles commented on BEAM-7951:
---------------------------------------

Is this an important release blocker? I am going to remove Fix Version here because we use it to indicate whether something blocks a release and this seems to be a feature request or project tracking ticket.

> 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)
