了解DocumentDB响应标头中的x-ms-resource-usage [英] Understanding the x-ms-resource-usage in DocumentDB response header

问题描述

在通过ID执行简单的Get操作(返回单个文档(而不是包含一个文档的数组))时，我得到以下x-ms-resource-usage:

While performing a simple Get operation by Id where a single document is returned (not an array with one document) I get the following x-ms-resource-usage:

x-ms-resource-usage:documentSize:0;documentsSize:288;collectionSize=307;

问题:

• 为什么documentSize 0?
• 度量单位是什么?字节?
• documentSize和documentsSize有什么区别?请注意，查询仅返回一个文档.
• 什么是collectionSize?那是馆藏中的文件总数吗?
• x-ms-resource-usage和x-ms-resource-quota有什么区别?

• Why is documentSize 0?
• What is the unit of measure? Bytes?
• What is the difference between documentSize and documentsSize? Please note the query only returns one document.
• What is the collectionSize? Is that the total number of documents in the collection?
• What is the difference between x-ms-resource-usage and x-ms-resource-quota?

推荐答案

我相当确定这些数字如下，并且全部以KB为单位:

I'm fairly sure the numbers are as follows, and all in KB:

• documentSize:文档的大小
• documentsSize:集合中所有文档的合并大小
• collectionSize:集合中所有文档的总大小以及索引之类的开销

• documentSize: Size of the document
• documentsSize: Combined size of all documents in collection
• collectionSize: Combined size of all documents in collection, along with overhead such as indexes

x-ms-resource-usage与集合中消耗的资源有关，而x-ms-resource-quota将为您提供限制.因此，有了配额，您会看到documentsSize和collectionSize都设置为10485760，即10GB(10,485,760 MB).

x-ms-resource-usage is about consumed resources within the collection, while x-ms-resource-quota is going to give you your limits. So with quota, you'll see documentsSize and collectionSize both set to something like 10485760, which is 10GB (10,485,760 MB).
