今天看到MySQL5.5放出了第一个版本 MySQL 5.5 Community Edition - Milestone Release，最大的增强莫过于加入了 Semi Sync Replication的支持（虽然仍不完善）。 这里做一个科普，简单介绍一下Semisynchronous Replication： 一、Why Semisynchronous Replication? 之前版本的MySQL Replication都是异步（asynchronous）的，主库在执行完一些事务后，是不会管备库的进度的。如果备库不幸落后，而更不幸的是主库此时又出现Crash（例如宕机），这时备库中的数据 ...
