Work Description: reuvenlax commented on issue #8006: [BEAM-6772] Change
Select semantics to match what a user expects
URL: https://github.com/apache/beam/pull/8006#issuecomment-477684178
FYI by "distribute array selects" I mean the following:
if you have { a: {b: int, c: int}[] } and someone select "a.b", "a.c" the
result should be {b: int[], c: int[]}. The same should be true if someone
selects a.*. However if someone selects just a, you get the original schema
back.

> Project: Beam
> Issue Type: Sub-task

> 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.
