Still getting into setting up models with Doctrine2 and testing as I go...

It is my understanding that the @DiscriminatorColumn annotation defines a table column in the underlying table (i.e. when run through SchemaTool).

If this is correct, shouldn't @DiscriminatorColumn support the columnDefinition attribute? This would allow this field to be setup as an ENUM in MySQL, for example... i.e.

/****
 * @Entity
 * @InheritanceType("JOINED")
 * @DiscriminatorColumn(name="discr", type="string", columnDefinition="ENUM('foo', 'bar', 'baz')")
 * @DiscriminatorMap({"foo" = "FooEntity", "bar" = "BarEntity", "baz" = "BazEntity"})
 */
class ParentEntity {
    // ...
}
