What is the difference between TreeCache and TreeCacheAop?
Think of TreeCacheAop as a TreeCache on steroid. 🙂 Seriously, both are cache store. However, while TreeCache only provides pure object reference storage (e.g., put(FQN fqn, Objecy key, Object value)), TreeCacheAop goes beyond that and performs fine-grained field level replication object mapping and relationship management for a user behind the scene. As a result, if you have a complex object systems that you would like to cache, you can have TreeCacheAop manages for you. You simply treat your object systems as they are residing in-memory, e.g., use your regular POJO methods without worrying about cache management. Furthermore, this is true in replication mode as well.
