Can you do me favor and use forms at http://community.jboss.org/en/teiid?view=discussions for questions. It has better formatting for code and easily searchable than mailing list. Thanks.

These are connection properties that may be dynamic in nature, that *may* influence the how query results are generated based if passed to translator. Once the VDB is built, the generation of the results is defined, and should be same for all users. So, no per user properties. If you defined properties in your 'ExecutionFactory' as defined here http://docs.jboss.org/teiid/7.0.0/developer-guide/en-US/html_single/#d0e516 using @TranslatorProperty, then those properties can be supplied through "vdb.xml". For example, say you defined "foo" property and its get/set methods, then in "vdb.xml" (check the additional "translator" fragment) <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <vdb name="imageVDB" version="1"> <property name="UseConnectorMetadata" value="cached" /> <model name="Images"> <source name="mysql" translator-name="mysql" connection-jndi-name="java:imageDS"/> </model> <translator name="extended-mysql" type="mysql"> <property name="foo" value"bar"/> </translator> </vdb> The value will be injected into your translator at invocation time. Seems like this is missing from our docs. can you log JIRA on that, we will update. Thanks Ramesh..
