> Project: Beam
> Issue Type: Sub-task
> Components: sdk-java-core
> Reporter: Reuven Lax

> Consider the following schema:
> User:
> name: STRING
> location: Location
>
> Location:
> latitude: DOUBLE
> longitude: DOUBLE
>
> If you apply Select.fieldNames("location"), most users expect to get back a
> row matching the Location schema. Instead you get back an outer schema with a
> single location field in it. Select should instead unnest the output up to
> the point where multiple fields are selected.
