Firestore 集合的最大深度是多少？
What is maximum depth of Firestore collection?
我在 Firebase Firestore documentation 上看到 "Maximum depth of subcollections" 的限制是 100。
这是指一个合集总共可以有多少个子合集？喜欢 /collection/document/sub1/document、/collection/document/sub2/document 一直到 /collection/document/sub100/document?
或者这是否以会使文件路径变长的方式引用它？例如：/collection/document/sub1/document/sub2/document/.../sub100/document?
Does this refer to the number of sub-collections that one collection can have in total?
不是，是不是是指一个集合总共可以有多少个子集合，是指你可以加深的子集合个数, 最多为 100.
Or does this refer to it in the way that would make the file path longer? For instance: /collection/document/sub1/document/sub2/document/.../sub100/document?
是的，这是正确的方法。
另请注意，Firestore 在级别 1 和级别 100 时一样快。
