Brian Hulette updated BEAM-9574:
--------------------------------
Description:
Attempting to pickle an instance of a generated NamedTuple class results in the
following:
{code}
_pickle.PicklingError: Can't pickle <class
'apache_beam.typehints.schemas.BeamSchema_a7de91e0_ae11_4c52_a041_0b58ada35ac1'>:
attribute lookup BeamSchema_a7de91e0_ae11_4c52_a041_0b58ada35ac1 on
apache_beam.typehints.schemas failed
{code}
In general, we shouldn't be pickling these instances, but occasionally it may
be necessary, and we should just do it rather than failing hard.
