synchronous replication

基本解释

Synchronous failover availability comes in two types: specialized HA software and synchronous replication.
同步故障轉移可用性有兩種類型：專門化的 HA 軟件和同步複制。
In many environments, synchronous replication is not a valid option because of the performance impacts of a synchronous implementation.
在很多情況下，同步複制都不是有傚的選項，因爲同步實現對性能影響非常大。
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.
同步複制意味著JVM退出時，沒有數據丟失，但由於主進程必須等待獲得變更信息的複制品，因此速度會慢一些。
