[teiid-issues] [JBoss JIRA] Commented: (TEIID-502) Allow Multiple UDF Definition Models

[Ramesh Reddy (JIRA)]

    [ https://jira.jboss.org/jira/browse/TEIID-502?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12510179#action_12510179 ] 

Ramesh Reddy commented on TEIID-502:
------------------------------------

By allowing the user to have a "FunctionDefinition.xml" per VDB this can be solved. However this removes support for the global "FunctionDefinitions.xmi". Also this aids to deploy the UDF module in single VDB artifact. User who are using the this UDF in global nature can get same features by adding this file to every VDB they are used in. Any supporting JAR file needs to be in the "lib" directory of the Container.

> Customer feature request from Issue Tracker ticket# 228151:
> The current mechanism for UDF (user-defined functions) is limited to having one model (FunctionDefinitions.xmi) in which UDF are defined and related to their Java implementations. This results in a configuration management problem even on just one project. For multiple projects it becomes a nightmare, unless we abandon all hope of building a body of reusable UDFs. I would therefore suggest that designer and server need to support multiple UDF definition models, identified by the extensions already defined and used for FunctionDefinitions.xmi.
