You can load the Materialized views through "execute SYSADMIN.refreshMatView(...)" call. In the Teiid engine, since the operations are occurring in asynchronous manner is difficult to schedule these jobs automatically at start. So, all you need a simple scheduler to execute above command.
You can submit a feature request if you want, then we can determine that is feasible.
Thanks. We are already doing that. I will submit a feature request.
