At last, an efficient memory consistencyprotocol is also designed and realized.
最后，设计并实现了高效的数据一致性维护机制。

But the memory consistencyprotocol will use system resources, has effect on system performance.
但一致性协议的使用也将占用系统资源，影响程序的运行速度。

Were these the only factors under consideration, a distributed transaction using the 2pc protocol would be the best approach to guarantee data consistency and integrity.
