摘要
为了多个数据服务节点间的数据同步能找到唯一数据源,提出了一种多节点主备切换设计方法。通过多个数据服务节点中选出最优节点作为主节点,避免了多点修改导致的数据冲突。该设计方法支持自动和人工切换方式,在大量节点故障的情况下可提供主备切换支持。
To find the only data source for data synchronization from many data service nodes, a design method of main/standby status switch for muhi-node system is presentcd. By selecting the best node as the main node from all data service nodes, the design avoids the data conflict from writing data in many nodes at one time. The method supports the auto-switch and the manual switch. It can work well when many nodes are down.
