I think I said this before, having preview working with multiple servers
IMO useless. Designer should work with single Teiid for preview. DTP is
different case, there you could work with multiple Teiid servers.

Also, I think in case when you are not creating the binding
automatically at the end of the import, you should start the create
connector binding wizard. So, there will never be the case model is
created but the binding is not. Obviously, this model breaks down when
the Teiid is offline. However, the binding needs to be created before
the model makes over to the Teiid

The model based indexes were being created currently. Type based indexes
are created when VDB is created.

Teiid does not care about name.
