Analysis

Overview

Different kind of resources are going to be persisted on th Sophie2 server - users, books, etc. For now, resources are stored in a database. We should not allow this database to be bloated, so a way for cleaning it up must be defined.

Task requirements

Design and implement a model for S2S database archiving. Think about the following aspects:

• Archiving old resource changes.
• Dealing with old comments.
• Archiving unused accounts.
  

Make decisions on these and apply them to the org.sophie2.server.persistence layer.

Task result

Source code - extra features in org.sophie2.server.persistence.

Implementation idea

1st: Implement this task after (or together with) S2S_PERSIST_CHANGES_R0?. The problem here is that this task is in the next revision.
2nd: Think out just the mechanism for archiving, apply it to the currently persisted objects. Changes' shrinking can be implemented with the next (main) revision.
