------------------------------------
Summary: Pickling Generated NamedTuple instances drops custom
members
Key: BEAM-10980
URL: https://issues.apache.org/jira/browse/BEAM-10980
Project: Beam
Issue Type: Bug
Components: sdk-py-core
Reporter: Brian Hulette
Assignee: Brian Hulette
We assign a custom {{__reduce__}} method and a {{_beam_schema_id}} member to
generated NamedTuple instances, but these methods are dropped when the
constructor is pickled and unpickled (as might happen when used in a closure
with beam.Map or beam.FlatMap)
