Object stored in WSAF Caching can be automatically removed from a cache through an expiration (due to a timeout) or eviction
(due to memory consumption). Evictions are based on an LRU (least recently used) policy so that the most active objects are
retained.
ScaleOut StateServer
SOSS also provides expirations and evictions. Timeouts can be either absolute or sliding. Evictions, like WSAF, use an LRU
algorithm when removing objects. Also, objects can be given priority with respect to eviction, allowing high-priority objects to remain in the store in low-memory scenarios.
