Igor Seliverstov commented on IGNITE-10559:
-------------------------------------------
[~tledkov-gridgain], see my comments below:
1) {{PartitionResult#calculatePartitions}} - in case a user has provided an
explicit partitions list it's makes sense do not use it as is, but calculate an
intersection with partitions going from {{PartitionResult}}
2) {{UpdatePlanBuilder.java:856}} {{qry.derivedPartitions() != null ?
qry.derivedPartitions() : null}} - looks like it may be simplified.
3) Imports + visa required.
> MVCC TX: Use extracted partitions to reduce target nodes for Query Update

> 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.
