Steven Hawkins commented on TEIID-4498:
---------------------------------------
The first issue with select subquery handling is that when subquery unnest defaults to
true, we can plan a join plan. If it's false there isn't the later handling of
the subquery - which is in RuleMergeCriteria for where subqueries.
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.
