Hmm, the spec may not be clear enough on this, but if you move a child and release the parent, then the other children are not usable anymore. In your case, you don't call release() on every child. You just call release() on the parent once you are done with all children. So the synchronization has to be managed on the consumer side, the producer doesn't see any of it. (and of course, the simplest way to do that in C++ may be to use a shared_ptr to an object holding the ArrowArray struct) Regards Antoine.
