* The Configurable interface indicates that the class can be instantiated by reflection. And it needs to take some configuration parameters to configure itself.
* The TableCreationHook is responsible for preparing the location to store the content of the cached table and map the table name to fields in the configuration so that the TableSinkFactory/TableSourceFactory can understand. 
* The TableCleanupHook is responsible for deleting the content of the cached tables and reclaim the space.
