Hi Markos, 6.2 adds a dynamic vdb feature that creates the metadata for vdbs at runtime, see http://www.jboss.org/community/wiki/QuickStartExampleUsingConnectorsuppli... for a quick start. The only issue you may have is controlling the recreation of the vdb. Currently we support cached for the lifetime of Teiid and cached until deleted. If you need more runtime control, please create a JIRA issue.

Can I use Teiid to apply SQL on these CSV files? In the documentation I read in the Quickstart Guide that I need a VB, and that I need the Designer for this. Can I not create a VB at runtime?
