def bake_lazy_loaders():

Enable the use of baked queries for all lazyloaders systemwide.

The "baked" implementation of lazy loading is now the sole implementation for the base lazy loader; this method has no effect except for a warning.

def unbake_lazy_loaders():

Disable the use of baked queries for all lazyloaders systemwide.

This method now raises NotImplementedError() as the "baked" implementation is the only lazy load implementation. The :paramref:`_orm.relationship.bake_queries` flag may be used to disable the caching of queries on a per-relationship basis.
