I'm not sure if it's relevant (probably not) but I've just noticed this warning: > /opt/airflow/airflow/models/serialized_dag.py:120 SAWarning: TypeDecorator UtcDateTime(timezone=True) will not produce a cache key because the ``cache_ok`` attribute is not set to True. This can have significant performance implications including some performance degradations in comparison to prior SQLAlchemy versions. Set this attribute to True if this type object's state is safe to use in a cache key, or False to disable this warning.
