Teiid Designer is design time tool, so it will not be involved in the scenario. All the management of "Data Change Capture" is external to Teiid and does not provide any built in support for it. The above is one possible suggestion as to how one can achieve it.  Since Teiid is running inside the JBoss AS server, integrating with other technologies is possible, like JBoss Fuse to capture the messages and route it back to Teiid.  Not sure about implementation details though.
