Hello, According to the doc <http://docs.doctrine-project.org/projects/doctrine-orm/en/latest/reference/inheritance-mapping.html#id4> :
If the target-entity of a many-to-one or one-to-one association is a CTI > entity, it is preferable for performance reasons that it be a leaf entity > in the inheritance hierarchy, (ie. have no subclasses). Otherwise Doctrine > *CANNOT* create proxy instances of this entity and will *ALWAYS* load the > entity eagerly. Let's say Cat and Dog extend from Animal (Class Table Inheritance) and I'd like both of them to have Fleas. I'll therefore declare an "animal" field in my Flea entity and make it *@ManyToOne(targetEntity="Animal")*. Note that in my whole model, no association is declared towards Flea (no "fleas" field in Animal, Cat or Dog, for instance). Are the following assumptions correct, please? - when I fetch Fleas from my FleaRepository, there will be a performance impact: the corresponding Animal will always be fetched because Doctrine must know its type (Cat or a Dog) - any other query to fetch any other entity won't be impacted, as none points at the Flea entity. For instance, a Cat object has no inverse relationship to Flea, so no performance impact. Thanks -- You received this message because you are subscribed to the Google Groups "doctrine-user" group.
