In distributed system, redundant data is the means of guaranteeing reliability, so the consistency maintenance of redundant data is very important. In general, a write operation must update all redundant data to be called a successful end. For example, a data on 5 devices have redundancy, because do not know the reading data will fall on which device, then a write operation, must be 5 devices are updated to complete, write operations to return.For systems with frequent write operations, the bott
