问题描述
对于我在 JavaScript 查询中使用的每个 orderByChild，我都会从 Firebase 收到此警告消息:
I get this warning message from Firebase for every single orderByChild I used in my queries from JavaScript:
FIREBASE 警告:使用未指定的索引.考虑在您的安全规则中添加 ".indexOn": "" at/tables 以获得更好的性能
FIREBASE WARNING: Using an unspecified index. Consider adding ".indexOn": "" at /tables to your security rules for better performance
到目前为止，我的查询运行得非常快，所以我认为没有必要包含 indexOn.只是想知道有什么负面影响?
So far my queries ran quite fast so I think it is not necessary to include the indexOn. Just wondering what are the negative impacts?
另外，我如何真正禁用警告，因为它们在我调试时非常烦人.
Also, how do I actually disable the warnings as they are quite irritating when I am debugging.
推荐答案
如果您处于开发阶段，您不会感觉到差异.但随着数据的增长，索引有助于加快查询速度.
If you are on development phase, you won't feel the difference. But as your data grows indexing helps making your queries much faster.

据我所知，要禁用警告，您必须编辑 firebase 源代码.有没有办法禁用所有firebase日志记录到控制台?
As far as I know to disable the warnings, you have to edit firebase source code. Is there someway to disable all firebase logging to console?
