Steven Hawkins commented on TEIID-4498:
---------------------------------------
After some experimentation, it's possible to just nest the dependent set criteria when
re plan the subquery. So I should have this by tomorrow at least for the simple case.
The more complicated case of multiple rows will take some more work. This will introduce a
new rule so that the subquery logic is consolidated and moved out of rule merge criteria.
Generalize subquery batch processing
------------------------------------
Key: TEIID-4498
URL: https://issues.jboss.org/browse/TEIID-4498
Project: Teiid
Issue Type: Enhancement
Components: Query Engine
Reporter: Steven Hawkins
Assignee: Steven Hawkins
Priority: Major
Fix For: 12.0
For subqueries that cannot be unnested, but can be modified to project their correlation,
we should have at least batch processing rather than the row by row default.
