Dmitry Kiriy updated IGNITE-10703:
----------------------------------
Description:
Currently drainTo(Collection<T> to, int amount) implemented as cyclic call of
poll() method, which is ineffective.
Need to be implemented as truly batch operation - trying to read required
amount of data at once.
current design prevent high-performance data transfer cross queue.
P.S. addAll implemented as batch, so together with right drainTo
implementation, it will be complete high-performance batched read&write queue
solution
