Package org.dspace.ctask.replicate.store

Class MountableObjectStore

java.lang.Object

org.dspace.ctask.replicate.store.LocalObjectStore

org.dspace.ctask.replicate.store.MountableObjectStore

All Implemented Interfaces:

ObjectStore

public class MountableObjectStore
extends LocalObjectStore

MountableObjectStore uses a mountable file system to manage replicas or other content. As such, it is not intended to provide the level of assurance that a remote, externally managed service can provide. It's primary use is in testing and validating the replication service, not as a production replica store. Note in particular that certain filesystem limits on number of files in a directory may limit its use. It stores replicas as archive files. Also note that MountableObjectStore differs only from LocalObjectStore in that all objects are copied, rather than moved (renamed). This will result in slower performance, but may be required when more complex storage architectures (e.g. an NFS-mounted store) are used.
