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 > ------------------------------------------------------------------------- > > Key: IGNITE-10559 > URL: https://issues.apache.org/jira/browse/IGNITE-10559 > Project: Ignite > Issue Type: Task > Components: mvcc > Reporter: Igor Seliverstov > Assignee: Taras Ledkov > Priority: Minor > Labels: iep-24 > Time Spent: 10m > Remaining Estimate: 0h > > 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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
