Firebase拥有100万个节点的读取操作限制 [英] Firebase 100 Million nodes in read operation limit
问题描述
你可能指的是这个页面: https://www.firebase.com/docs/rest/guide/understanding-data.html
该页面包含一个名为限制和限制的表
子节点的深度32
密钥长度768字节UTF-8编码,不能包含。 $ [] /或ASCII控制字符0-31或127
一个子值的大小10mb UTF-8编码
从SDK写入16mb UTF-8编码
从REST 256mb写入
读取操作中的节点数亿元
这是指您正在阅读的JSON结构中的节点(元素)。 / p>
即,以下的JSON对象: {id:1,name:John Doe}
包含两个节点, id
和名称
。该对象本身就是父节点,共有3个。
以下的JSON数组:
[{id:1,name:John Doe},{id:2,name:Jane Doe}]
包含2x3个节点加上array = 7个节点。
The firebase docs say that nodes in read operation limited to 100 million. What nodes is this limitation referring to?
You are probably referring to this page: https://www.firebase.com/docs/rest/guide/understanding-data.html
The page contains a table called "Limitations and Restrictions"
Depth of child nodes 32
Length of a key 768 bytes UTF-8 encoded, cannot contain . $ [ ] / or ASCII control characters 0-31 or 127
Size of one child value 10mb UTF-8 encoded
Write from SDK 16mb UTF-8 encoded
Write from REST 256mb
Nodes in a read operation 100 million
This refers to the nodes (elements) in the JSON structures you are reading.
I.e. the following JSON object: {"id": 1, "name": "John Doe"}
contains two nodes, id
and name
. The object itself is the parent node, making a total of 3.
The following JSON array:
[ {"id": 1, "name": "John Doe"}, {"id": 2, "name": "Jane Doe"}]
Contains 2x3 nodes plus the array = 7 nodes.
