> Project: Ignite

>
> Current implementation of the {{lazy}} mode always starts separate thread for {{MapQueryLazyWorker}}.
It causes excessive overhead for requests that produces small results set.
> We have to begin execute query at the {{QUERY_POOL}} thread pool and fetch first page
of the results. In case results set is bigger than one page {{MapQueryLazyWorker}} is started
and link with {{MapNodeResults}} to handle next pages lazy.
