>Impact on custom XCOM backends. Flow: >TLDR: Custom XCOM backends store the "path" to the xcom object remotely stored in the DB as a JSON type, but store the data at that "path" without serialisation (as JSON objects). So the interface to interact with this backend is in JSON objects, which is what the new proposed flow above does precisely. Not always, example `XComObjectStorageBackend` only stores value in a remote object if it is greater than a certain threshold, for others it serializes the objects into string using `json.dumps` https://github.com/apache/airflow/blob/8f63b828ace09b1095229f22b0c6d1f0f85ea81a/providers/common/io/src/airflow/providers/common/io/xcom/backend.py#L116-L118 -- This is an automated message from the Apache Git Service.
