这通常是性能倒数第二的策略，因为它要求有缓存锁，缓存集群中使用重量级的“推”更新策略。

This is usually the second worst performing strategy due to its cache lock requirement and the heavy "push" update policy for clustered caches.

如果缓存是一个集群，“更新缓存”的调用会将新值推送给所有副本，这通常被称为“推(push)”更新策略。

If the cache is clustered, the "updates cache" call will push the new value to all replicates, which is often referred to as a "push" update policy.
