Several of one's structure variations will reflect The reality that the Table service is intended to help cloud-scale purposes that will consist of billions of entities (rows in relational databases terminology) of data or for datasets that must assistance very superior transaction volumes: consequently, you might want to think in a different way regarding how you keep your data and know how the Table company is effective.
