单调写一致性。
因为已经开启了镜像写一致性检查(MWC)，所以如果卷位于边缘，那么应该能够更好地为其提供服务。
Because Mirror Write Consistency (MWC) is on, the volume would have been better served if it were placed on the edge.
然而，这也是一个成本较高的选择，因为每当您跨集合内容进行迭代时，您就不得不同步所有操作，包括读和写，以此保证一致性。
That's also a costly option, however, because every time you iterate across the contents of the collection, you have to synchronize all operations, including read and write, to ensure consistency.
但这也是有代价的，那就是增加了写延迟，同时API中的一致性保证也发生了变化。
This was achieved at the expense of increased latency for writes and changes in consistency guarantees in the API.
这能让你在维持相当高的写可用性的同时，拥有强一致性特性，这对一些用例来说非常重要。
This approach allows you to have strongly consistent characteristics, which are important for a number of use cases, while still maintaining a very high level of write availability.

从纯数据的角度来看，eBay可以被描述为具有大量的读、写操作，但对容错性和一致性的要求非常严格。
From a pure data perspective, eBay can be described as having a huge number of frequent writes, as well as reads, with an extremely low tolerance for error or inconsistency.
数据同步方面系统采用了域一致性模型、多写协议，和基于锁的同步方式；
The system of this thesis employs scope consistency model, multi-write and lock-based cache protocol. In communication module, we propose a new framework.
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.
