entity
Description copied from interface:DeferredSaver
Save a single entity in the datastore at the end of the current unit-of-work.
This method can be called multiple times on a single entity; that will produce a single save. If deferred saves and deletes are applied to an entity, the last one wins.
If the entity has a null Long id, the value will be autogenerated and populated on the entity object when the operation completes. Since this is a deferred operation, that will be past the end of your unit-of-work (transaction boundary).
Saves do not cascade.
