[jira] [Commented] (IGNITE-14703) Add merge-sort reducer for cache queries.

    [ https://issues.apache.org/jira/browse/IGNITE-14703?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17411904#comment-17411904 ] 

Andrey Mashenkov commented on IGNITE-14703:
-------------------------------------------

[~timonin.maksim], now looks much better.
I've left few comments to the PR.

Please, just keep in mind, there may be 1k+ nodes in the grid.
So, having redundant collections or iterating over collections may cost a bit.
