synchronous replication

基本解釋

Synchronous failover availability comes in two types: specialized HA software and synchronous replication.
同步故障轉(zhuǎn)移可用性有兩種類型：專門化的 HA 軟件和同步復制。
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，同步復制都不是有效的選項，因為同步實現(xiàn)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.
同步復制意味著JVM退出時，沒有數(shù)據(jù)丟失，但由于主進程必須等待獲得變更信息的復制品，因此速度會慢一些。
