to {{true}}.
> Use lazy mode with results pre-fetch
> ------------------------------------

> Key: IGNITE-9171
> URL: https://issues.apache.org/jira/browse/IGNITE-9171
> Project: Ignite
> Issue Type: Improvement
> Components: sql
> Affects Versions: 2.6
> Reporter: Taras Ledkov
> Assignee: Taras Ledkov
> Priority: Major
> Labels: sql-stability
> Fix For: 2.7
>
>
> 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.
