[dna-issues] [JBoss JIRA] Updated: (DNA-160) Create pluggable merge processor that contains the logic of how to merge multiple nodes into one node

Create pluggable merge processor that contains the logic of how to merge multiple nodes into one node ----------------------------------------------------------------------------------------------------- Key: DNA-160 URL: http://jira.jboss.com/jira/browse/DNA-160 Project: DNA Issue Type: Sub-task Components: Federation Reporter: Randall Hauch Assigned To: Randall Hauch Fix For: 0.2 A FederatedRepository instance should use a MergeProcessor implementation to actually do all the merging operations; the FederatedRepository is then responsible for managing the integrated repository (cache), adhering to the cache policies, making the requests to the sources, calling the MergeProcessor, and then storing the merged node back in the cache. It is very likely that the merge logic will evolve significantly over time, and that some uses of DNA may even require their own (perhaps optimized) processing logic. I believe there is even an opportunity to provide a Drools-based processor that uses rules to perform the work. This obviously won't be the first implementation, but could be one of the most powerful and capable processor implementations.
