Firestore 定价 - 集合中的文档数量重要吗? [英] Firestore Pricing - Does The Amount Of Documents In A Collection Matters?

问题描述

我已在文档中阅读我需要支付的费用我对 read、write 或 update documents 的请求.我还读到，阅读 collection 的价格与阅读 document 的价格相同(对于文档读取以外的查询，例如对列表的请求的集合 ID，您需要为阅读一份文档付费.")，如果我错了，请纠正我.

我的问题是:阅读包含大量 documents 的 collection(比如说 - 10,000 个 documents)是否需要花费和 10 读一读一样吗?

我想得到一些关于它的解释...

解决方案

这取决于读取集合"的含义，但对于大多数人来说，这意味着从集合中查询一堆文档".答案是定价通常取决于检索的文档数量.

把事情简单化一点:

如果您有 10 个员工的集合，并且您运行 collection("employees").get() 调用，您将获得 10 个员工文档，并收取 10 次读取费用.

如果您有 10,000 名员工的集合，并且您运行 collection("employees").get() 调用，您将收回 10,000 名员工，并收取 10,000 次读取费用.>

如果您有 10,000 名员工的集合，并且您运行 collection("employees").get().limit(10) 调用，您将收回 10 名员工，并收取10 次阅读.

如果您有 10,000 名员工的集合，其中 4 名名为Courtney"，并且您运行了一个 collection("employees").where("first_name", "==", "Courtney") 调用，你会找回 4 名员工，并收取 4 次读取费用.

I have read in the documentation that I'm being charged for the amount of the requests I'm making to read, write or update documents. I have also read that reading a collection is priced the same as a reading a document ("For queries other than document reads, such as a request for a list of collection IDs, you are billed for one document read."), correct me if I'm wrong.

My question is: Does reading a collection with a big amount of documents in it (let's say - 10,000 documents) is priced the same as reading one with 10?

I'd like to get some explaination about it...

解决方案

It depends on what you mean by "reading a collection", but for most people this means "querying a bunch of documents from a collection". And the answer is that the pricing generally depends on the number of documents retrieved.

To oversimplify things just a bit:

If you have a collection of 10 employees and you run a collection("employees").get() call, you will get back 10 employee documents, and be charged for 10 reads.

If you have a collection of 10,000 employees and you run a collection("employees").get() call, you will get back 10,000 employees, and be charged for 10,000 reads.

If you have a collection of 10,000 employees and you run a collection("employees").get().limit(10) call, you will get back 10 employees, and be charged for 10 reads.

If you have a collection of 10,000 employees, 4 of which are named "Courtney" and you run a collection("employees").where("first_name", "==", "Courtney") call, you will get back 4 employees and be charged for 4 reads.
