/**
 * A key factory which helps implementations leverage 
 * table and data graph specific configuration information,
 * such as the hashing algorithm and field level row and column
 * model settings. 
 * 
 * The initial creation and subsequent reconstitution for query retrieval
 * purposes of both row and column keys in CloudGraph™ is efficient, 
 * as it leverages byte array level API in both Java and the current 
 * underlying SDO 2.1 implementation, PlasmaSDO™. Both composite row and 
 * column keys are composed in part of structural metadata, and the 
 * lightweight metadata API within PlasmaSDO™ contains byte-array level, 
 * cached lookup of all basic metadata elements including logical and 
 * physical type and property names.
