[jira] [Commented] (BEAM-8849) Flink: Support multiple translation of a single URN in batch runner.

    [ https://issues.apache.org/jira/browse/BEAM-8849?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17120274#comment-17120274 ]

------------------------------------

Maybe not worth to generify this yet but it would be neat if we can think on a solution that could be consistent for other runners too (Spark).

> We need to be able to have multiple translations for a single URN (right now we want to have a special translation for GBK with non-merging windowing). We'll introduce a new `canTranslate` method for all translators, that can be used by runner to decide, which translation to use based on `PTransform` properties.
