Hi,
I've been trying to better understand the properties of different Postgres JSON field implementations. I wrote s script with my tests and I thought I would share it. It can be found at:
FWIW, I found implementing the field as Column(sqlalchemy_json_NestedMutable.as_mutable(pg_JSONB)) had the mutation tracking and querying I was looking for.
I hope this is of use to someone :)
