5899bb3CompareThe serialized DAG dictionary is not ordered correctly when creating hashes, and that causes inconsistent hashes, leading to frequent update of the serialized DAG table. Changes: Implemented sorting for serialized DAG dictionaries and nested structures to ensure consistent and predictable serialization order for hashing. Using `sort_keys` in `json.dumps` is not enough to sort the nested structures in the serialized DAG. Added serialize and deserialize methods for DagParam and ArgNotSet to allow for more structured serialization. Updated serialize_template_field to handle objects that implement the serialize method. This was done because of DagParam and ArgNotSet in the template fields. Previously, it produced an object, but with this change, it now serialises to a consistent object.

There was a problem hiding this comment.
Looks reasonable enough to me.
