If your connection is stale, or even worse when your connection to a datasource is offline/not available.
But you do have views working on top of these datasources.
Is it possible for Denodo to give you a "select X from dual()" dummy record back instead of giving a "incomplete results" or "HTTP-error 404" or "JDBC route unexpected error"?
so even if a datasource is unavailable, you could still complete your query without getting errors?
