Hi *, I wonder if it is possible and supported in SQLAlchemy to query an instance by identity key.
Use case: I want a length operation to run in an extra process. That means I will need an extra database connection in that process and have to retrieve the objects I am working with again. To implement this in a generic way, I want to ask sqlalchemy about the identity key of the instance (using sqlalchemy.orm.util.identity_key). Using that key, I can retrieve the instance again in the new process. But where is the method that can do that? I was expecting something like session.get_instance_by_key(key) to be in the API, but I am unable to find it. Any hints?
