             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.
