I am learning database transaction in DDIA, There are two concepts of skew in this book, one is unbalanced workload with hot spots, the other is timing anomaly, I can not understand the meanning of 'timng anomaly' and why is called skew.

我在学习DDIA中的数据库事务,这本书中有两个概念,一个是工作负载不平衡的热点,另一个是时间异常,我不明白时间异常的意思,为什么叫时间异常。



The term skew is unfortunately overloaded: we previously used it in
the sense of an unbalanced workload with hot spots (see “Skewed
Workloads and Relieving Hot Spots” on page 205), whereas here it means
timing anomaly.



I want to kow how to explain the menaing of skew in this case

我想知道在这种情况下如何解释倾斜的威胁

Check your book, I'm sure it provides additional explanation.

查一下你的书,我肯定它提供了额外的解释。

@Shadow there are some read skew and write skew examples in book, but i can not relate those examples with skew

@Shadow书中有一些读歪斜和写歪斜的例子,但我不能把这些例子和歪斜联系在一起

Why can't you relate those examples with skew?

为什么你不能把这些例子和歪斜联系起来呢?

@Shadow I think those examples just describe some phenomenon, but I don not know why these phenomenon is called skew, I can't relate these phenomena tothe meaning of skew(or say I can't understand why is means timing anomaly.)

@Shadow我认为这些例子只是描述了一些现象,但我不知道为什么这些现象被称为Skew,我不能将这些现象与Skew的含义联系起来(或者说我不能理解为什么这意味着时间异常)。

This seems to be more of a linguistic problem then, not a programming one.

这似乎更多的是一个语言问题,而不是编程问题。
