[teiid-issues] [JBoss JIRA] (TEIID-2191) Detect recursive view definitions

[Steven Hawkins (JIRA)]

     [ https://issues.jboss.org/browse/TEIID-2191?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Steven Hawkins resolved TEIID-2191.
-----------------------------------

    Resolution: Done


Generalized the compensating physical update/delete planning loop check into a check for planning recursion with views/procedures.  See https://github.com/teiid/teiid/commit/7157c30e015b8c43f839bc50ff22e8c1b25f2b5b

The recursion check may need to be relaxed later to add support for recursive views and if we want to remove the procedure validation of recursion and not fully compose procedure plans prior to execution.

> A feature from designer that was never added to the runtime is detection of recursive view definitions.  Currently if a recursive view is supplied via ddl or translator it will cause a stackoverflow in the relational planner when it is accessed.
