Yes, "remodeling" the schema will be required to have good performance for new queries which things had not been cached ahead of time to accommodate.
In C*, you're going to pre-compute all caching ahead of time, in order to maximize performance. This is in contrast to the relational approach where you get whatever you want, but your performance may degrade when you do the costly joins.
