> In perform() of AbstractMaterializedViewRule, when we iterate through all 
> applicable materializations trying to rewrite the given query, extracting 
> view table references should shift to an earlier in loop to speed up 
> rewriting. Specially, it uses {{return}}  instead of {{continue}}. Is it a 
> mistake?
