[jira] [Created] (JCR-3389) Implement a MultiDataStore
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.

Marcel Reutegger reopened JCR-3389:
-----------------------------------
Claus, I noticed that your changes use tabs instead of spaces for indentation. Can you please fix that?
Also, woulnd't it be easier to use DocumentBuilder.newDocument().createElement() instead of implementing your own Element class?

First inital patch for the multi datastore. At the moment the param element could have a DataStore Element in it.
Its not generic but we can change this later if we realy need it i think.

---------------------------------
The GarbageCollector would only remove files from the archive datastore. Only the "archive task" would delete (move to archive datastore) files from the primary.
