在缓存数据的一致性是非常重要的场合下，可以通过Terracotta Server Array实现分布式的Ehcache，这样开发者就拥有了能够维护数据一致性的分布式缓存。

In cases where cache data consistency is important, Ehcache can be distributed using the Terracotta Server Array. This gives developers a distributed cache that maintains data coherence.

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.
