The real question behind your question is how do we achieve consistency? To achieve consistency in large scale systems, you have to give up on ACID and instead use base.

你的问题背后隐藏的真正问题是我们如何实现一致性？

youdao

Mnesia supports ACID (Atomicity, Consistency, Isolation and Durability), but also offers the ability to perform in memory only operations on tables (at the expense of durability).

Mnesia支持ACID（A=原子性，C=一致性，I=隔离性，D=耐久性），不过也提供仅限于内存的数据表操作能力（以牺牲耐久性为代价）。

youdao

This clearly violates the ACID (atomicity, consistency, isolation, durability) properties of a transaction (specifically the atomicity property).

这显然违背了事务的ACID (atomicity、consistency、isolation和durability)属性(特别是atomicity属性)。

youdao

The ACID properties (atomicity, consistency, isolation, durability) have been drilled into our heads.
