Date Tue, 17 Jul 2012 14:15:35 GMT
Claus Köll created JCR-3389:
-------------------------------

             Summary: Implement a MultiDataStore
                 Key: JCR-3389
                 URL: https://issues.apache.org/jira/browse/JCR-3389
             Project: Jackrabbit Content Repository
          Issue Type: New Feature
          Components: jackrabbit-core
    Affects Versions: 2.4.2
            Reporter: Claus Köll
            Assignee: Claus Köll


The idea of a multidatastore is to decorate two datastores. It can be used to implement a
Primary/Archive DataStore.
New binary files are saved into the primary. A archive task would move files from the primary
to the backup datastore. Reading from a MultiDataStore is transparent to the jcr api. So it
will always return files either from the primary or from the backup datastore.
The primary datastore can be mapped to a fast storage medium and the archive to a cheap sata
or a tape library.
