> For multi statement queries, in order to advance to the next statement we
> have to get sure that the first page of result for current statement is ready
> to be served. This allows not to depend on a user and finish the script even
> if no one consumes the results.
> Definition of done: there is an API available from within
> {{SqlQueryProcessor}} such that will allow to be notified about completion of
> prefetch ({{AsyncRootNode#prefetch}}).
