 Deleting an object with all its associated objects can be achieved
 in multiple ways with very different performance impacts.

    In both cases the cascade remove semantics are applied recursively.
    For large object graphs this removal strategy can be very costly.
 2. Using a DQL ``DELETE`` statement allows you to delete multiple
