ASF GitHub Bot logged work on BEAM-9574: ---------------------------------------- Author: ASF GitHub Bot Created on: 23/Mar/20 17:23 Start Date: 23/Mar/20 17:23 Worklog Time Spent: 10m Work Description: TheNeuralBit commented on pull request #11196: [BEAM-9574] Ensure that instances of generated NamedTuple classes can be pickled URL: https://github.com/apache/beam/pull/11196 Attempting to pickle an instance of a generated NamedTuple class results in the following: ``` _pickle.PicklingError: Can't pickle <class 'apache_beam.typehints.schemas.BeamSchema_a7de91e0_ae11_4c52_a041_0b58ada35ac1'>: attribute lookup BeamSchema_a7de91e0_ae11_4c52_a041_0b58ada35ac 1 on apache_beam.typehints.schemas failed ``` In general, we shouldn't be pickling these instances, but occasionally it may be necessary, and we should allow it rather than failing hard.
