Interface ConfigurableKeyFactory

All Known Implementing Classes:

ByteBufferKeyFactory, CompositeColumnKeyFactory, CompositeRowKeyExpressionFactory, CompositeRowKeyFactory, StatefullColumnKeyFactory

public interface ConfigurableKeyFactory

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.
