Vladimir Ozerov commented on IGNITE-10559:
------------------------------------------

[~tledkov-gridgain], [~gvvinblade], 
I would prefer to leave partition intersection logic as is for now. First, it 
is out of scope of this ticket. Second, it is broken anyway. Note that 
currently partitions are extracted for the whole query. But in reality they 
should be extracted for every map query separately. Cannot do this now easily 
due to protocol limitations. For this reason it doen't make sense to invest 
into proposed change as it is going to be reworked in future anyway.

> 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.
