Taras Ledkov commented on IGNITE-10559:
---------------------------------------

[~gvvinblade] I agree that explicit partition info may be reduced (use 
intersection) or validated (print warning) by partition info calculated from 
query.
[~vozerov], what do you thing about it? What behavior must be default? Should 
we add new property to choose behavior?

> We may avoid "query reduce" step on update queries without sorting/grouping 
> by simply sending them to all data nodes and executing update operation 
> locally. Using extracted from SQL partitions will reduce target nodes count 
> and save resources.
