[jira] [Commented] (IGNITE-12692) Calcite integration. DML. Skip reducer optimization.

["Igor Seliverstov (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/IGNITE-12692?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17039027#comment-17039027 ] 

Igor Seliverstov commented on IGNITE-12692:
-------------------------------------------

UPD seems it's more efficient and natural to request from a modify node underlying table distribution and add a single distributed SUM aggregation node before it - this way a planner will try to collocate modification and source select.

Adding a single distributed table modify to search scope as an alternative will cover a case when collecting phase required.

This way we'll get desired behavior automatically.

> Having plan tree we easily can check whether a final modification may be executed on data nodes directly or not. We should implement such kind of optimization.
