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.

如果是缓存集群，“清除缓存”调用会让所有副本都失效，这通常被称为“拉(pull)”更新策略。

If the cache is clustered the "evicts cache" call will invalidate all replicates, which is often referred to as a "pull" update policy.

分布式锁管理机制实现了GOS之间数据访问的同步协调，写通和写—无效的数据更新策略保证了GOS的缓存一致性。

The distributed lock system is used to synchronize GOS steps when accessing data. The consistency of the distributed cache is guaranteed by updating strategies of write-through and write-invalidate.
