Less frequently used objects can be stored only in the backing store, and retrieved into the cache as needed.
Note: Cache Plus Memory (Cache+Memory) mode is deprecated.
In a similar way, you can define how to manage the instances of each object type, using one of the following
cache modes:
- Cache Plus Memory
- Shown as “Cache+Memory” in the UI.
- In the Rete network as well as in the cache: Use for constants and concepts that change infrequently. In a concurrent system, Cache Plus Memory mode is inappropriate for most purposes, due to the difficulties involved in keeping all the concurrent processes synchronized.
- Cache Only
- Only in the cache, most commonly used mode for concurrent systems. The objects are retrieved into memory (the Rete network) only when needed for an RTC. Locking is still required as in any concurrent system.
- Memory Only
- Only in the Rete network, used for objects whose persistence is not important. Use for small, frequently used, stateless entities, for improved performance.
