bolkedebruin opened a new pull request, #27540: URL: https://github.com/apache/airflow/pull/27540
Datasets could not be passed as parameters to taskflow functions as they could not be serialized. This commit: 1) changes the xcom serializer so that it now can serialize objects that have attr 2) removes the need to for a custom serializer in lineage 3) adds a version check to the serializer/deserializer 4) registers any datasets as either inlets or outlets in the task Currently the deserializer is NOT compatible with the previous one used in lineage for the following reasons: 1) '__type' was overloaded (used as the encoding type AND actual type), the standardized deserializer can't figure out if it is seeing the actual type or encoded type as it receives the nested version first 2) '__source' is omitted, it seemed not to be used (could be wrong) @ashb @jedcunningham @kaxil <!-- Thank you for contributing!
