Interface HBaseKeyFactory

All Superinterfaces:

HiveStoragePredicateHandler

All Known Implementing Classes:

AbstractHBaseKeyFactory, CompositeHBaseKeyFactory, DefaultHBaseKeyFactory

public interface HBaseKeyFactory
extends HiveStoragePredicateHandler

Provides custom implementation of object and object inspector for hbase key. The key object should implement LazyObjectBase. User can optionally implement HiveStoragePredicateHandler for handling filter predicates
