--------------------------------
Summary: Select transform has non-intuitive semantics
Key: BEAM-6772
URL: https://issues.apache.org/jira/browse/BEAM-6772
Project: Beam
Issue Type: Sub-task
Components: sdk-java-core
Reporter: Reuven Lax
Assignee: 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.
