two-phase commit

基本解釋

First, find out if your environment meets the prerequisites to support two-phase commit.
首先，查看您的環(huán)境是否滿足支持兩堦段提交的先決條件。
If your application needs to access multiple resources as part of the same operation, you need two-phase commit transactions.
如果您的應(yīng)用程序在同一個操作中需要訪問多種資源，您就要使用兩堦段提交事務(wù)。
If another resource becomes involved in the transaction, you have forced an unnecessary two-phase commit, causing an additional prepare flow.
如果在事務(wù)中涉及另一項資源，就會強制進行不必要的兩堦段提交，導(dǎo)致額外的準備流程。
