> With the new off heap storage architectures (IGNITE-3477) it makes sense to improve a part of the system that prepares an SQL query result set in a such a way:
> - result set should consist of wrappers objects that incorporate off heap pointers to fields and values stored off heap;
> - during the time the result set is being sent over the wire we shouldn't move fields and values from off heap to Java heap but rather implement a solution that will allow us to pass an off heap pointer to a sockets output stream. Probably this can be done by leveraging Java's DirectBuffers.
