> Key: BEAM-7333

> Project: Beam
> Issue Type: Sub-task
> Components: sdk-java-core
> Reporter: Reuven Lax
> Priority: Major
>
> There needs to be a way to rename fields in Select - i.e. Select("field1").as("field2").
> While in many cases the RenameFields transform could be used, that doesn't help when a Select would return conflicting names - i.e. Select("a.c", "b.c"). In this case the Select transform would fail, because the output schema would have two fields of the same name.
