Federate/cache content from a remote JCR (and DNA) repository
-------------------------------------------------------------

                 Key: DNA-159
                 URL: http://jira.jboss.com/jira/browse/DNA-159
             Project: DNA
          Issue Type: Feature Request
          Components: Connectors
            Reporter: Randall Hauch
            Priority: Minor
             Fix For: Future Releases


The primary use case for this feature is to allow an application to have a local DNA repository that is configured to be a local, cached copy of a single remote JCR repository.  So, rather than having multiple sources, this use case would have a single source (using a connector to a remote JCR repository), and it would be configured to probably have a cache policy with a relatively short TTL.  (Of course the TTL could be extended if the connector could listen to the remote repository to receive events, which would be propagated up to the local "federated" repository and would cause those particular changed instances to be purged from the cache.

Ideally this could be made to be very lightweight and very easy to configure, maybe even using just an in-memory "integrated repository" (aka, cache).

This use case is far superior to an implementation that uses remote calls for every operation.
