[teiid-designer-issues] [JBoss JIRA] (TEIIDDES-1207) Merge the relational and function metamodels

Barry LaFond commented on TEIIDDES-1207:
----------------------------------------
Currently Extension properties are indexed and bookkept separate from Relational
(PHysical/Virtual) models. We could tweak our RuntimeAdapter class to actually add these
new "Function Extension" properties to the indexed "Relational
Procedure" and it's parameters.
... depending on, of course, the flexibility of Teiid server/runtime to handle this
change.
Merge the relational and function metamodels
--------------------------------------------
Key: TEIIDDES-1207
URL: https://issues.jboss.org/browse/TEIIDDES-1207
Project: Teiid Designer
Issue Type: Quality Risk
Components: Modeling
Affects Versions: 8.0
Reporter: Steven Hawkins
Having the function and relational models is no longer necessary. We can add the needed
function metadata (including TEIIDDES-152 vararg support, null-on-null, etc.) through
either extension properties or a metamodel change. This is in the vain of PostgreSQL
which uses the create function syntax to add what would be procedures in other dbmses.
Virtual functions (procedures marked as functions in a view layer) could also still
specify transformation sql if pushdown is not required - rather than forcing the use of a
java class.
We could deprecate the old function model support of the Teiid side then.
