Hi, 主 4G RAM, 100G SSD 从2G RAM, 100G SSD.
网站流量不大，读写都是由主机，从机仅仅是为了冗余备份。 问题： 这样能保证强一致性性吗？ PHP写操作要不要加fsync = true? thanks

No matter whether the traffic is large or not, it is best not to use master-slave in the wired network. Add one more machine to build a sharded cluster. Please refer to here /blog/dmyang/1190000002426743
