Marc/John,
Any update on what the user is doing here? 1 and 3 could be pursued without additional
fixes. 1a and 2 could also easily be pursued with 1a being preferential if the user does
not want to modify their queries and there is a general preference to not have the source
evaluate uncorrelated subqueries.

Virtual table mapping with large number of UNIONs is resulting in
excessively long source query

Project: Teiid
Issue Type: Bug
Components: Query Engine
Affects Versions: 7.4.1, 7.7

Queries against a virtual table built upon several layers of UNION transformations is
resulting in what appears to be a badly formed, excessively long source query (for
example, a SQL string over 1 million characters) that results in slow query execution.
