org.cloudgraph.store.mapping.DataField

public class DataField
extends KeyField

The settings for one data field within a composite row-key. Each data field maps a property within the data graph to a position within the composite row key, adding another "dimension" to the key. In HBase for example, this composite row-key approach enables the HBase partial row-key scan functionality which greatly improves query performance.
