All Implemented Interfaces:

BackendFactory

@ParametersAreNonnullByDefault
public class HBaseBackendFactory
extends AbstractBackendFactory<HBaseConfig>

A BackendFactory that creates HBaseBackend instances.

IMPORTANT: Transient back-ends can be instantiated using this factory, but they will be handed as persistent ones. This is a limitation that will be solved in next releases. To avoid any consistency issue we recommend every HBase resource right after their creation, ensuring the resource is using a persistent back-end.
