synchronous replication

基本解释

Synchronous failover availability comes in two types: specialized HA software and synchronous replication.
同步故障转移可用性有两种类型：专门化的 HA 软件和同步复制。
In many environments, synchronous replication is not a valid option because of the performance impacts of a synchronous implementation.
在很多情况下，同步复制都不是有效的选项，因为同步实现对性能影响非常大。
Synchronous replication means no data loss when a JVM exits but it is slower as the primary must wait for the replicas to acknowledge they have received the change.
同步复制意味着JVM退出时，没有数据丢失，但由于主进程必须等待获得变更信息的复制品，因此速度会慢一些。
