Firebase警告：使用未指定的索引 [英] Firebase warning: Using an unspecified index

问题描述

我从Firebase收到来自JavaScript的查询中使用的每个 orderByChild 的警告消息：

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/ table中添加.indexOn：表示安全规则以获得更好的性能

FIREBASE WARNING: Using an unspecified index. Consider adding ".indexOn": "" at /tables to your security rules for better performance

到目前为止，我的查询运行速度非常快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，我如何实际禁用警告，因为在我调试时它们非常烦人。

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，您将感受不到与众不同。但随着您的数据增长，索引有助于提高查询速度。

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。
有什么方法可以禁用所有firebase日志记录控制台？

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?
