OSCache 3.0

The primary goal of this release is to make OSCache more reliable and easier to use and maintain.

• Reliability and maintainability will be achieved by replacing the core cache storage classes with simpler ones that sync on coarse-grained cache operations. The memory cache, for instance, will use a hash map for its internal storage. Existing features will be provided at a higher level, so to avoid conflicting with the storage management logic.
• Usability will be improved through a refactored API that extends the java.util.Map interface. Some of the the things the new API will change:
  • Remove NeedsRefreshException (if you have to ask, then you shouldn't care).
  • Support for Object keys instead of only strings.
  • Support for cache regions to enable easier management of multiple caches.
  • Configuration via Spring (yes, it's a buzzword).
  • Administration and statistics.

Furthermore we discuss a Chain Caching Model internal.
