問題描述
對于我在 JavaScript 查詢中使用的每個 orderByChild，我都會從 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.考慮在您的安全規則中添加 ".indexOn": "" at/tables 以獲得更好的性能
FIREBASE WARNING: Using an unspecified index. Consider adding ".indexOn": "" at /tables to your security rules for better performance
到目前為止，我的查詢運行得非常快，所以我認為沒有必要包含 indexOn.只是想知道有什么負面影響?
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，因為它們在我調試時非常煩人.
Also, how do I actually disable the warnings as they are quite irritating when I am debugging.
推薦答案
如果您處于開發階段，您不會感覺到差異.但隨著數據的增長，索引有助于加快查詢速度.
If you are on development phase, you won't feel the difference. But as your data grows indexing helps making your queries much faster.

據我所知，要禁用警告，您必須編輯 firebase 源代碼.有沒有辦法禁用所有firebase日志記錄到控制臺?
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?
