Maksim Timonin updated IGNITE-14944:
------------------------------------
Description:
Currently onNodeLeft checks that left node is still running query, if it is
then we fail. But if query is limited then we can have enough data in page
buffer. So we can ignore such fail.
Also idea for limit optimization for MergeSort algorithm - add to comparison of
streams metric of probability of loading next page (try use as much local data
to avoid loading new pages): local node, size of current page for iteration.
