当前，我正在使用Azure for Students订阅，并且我一直在使用免费套餐来使用我的所有资源.我还阅读了此文档关于存储和吞吐量的信息，但是我不确定为了使一切正常运行，我需要修改什么.

Currently, I'm on an Azure for Students subscription and I've been using the free tier for all of my resources. I also read in this documentation on storage and throughput, but I'm not sure what I would have to modify in order to get things working.

有人可以建议吗?

推荐答案

文档的最大大小为2 MB，无法增加.在您的情况下，您可以将图像存储在Blob存储中，并将url作为属性附加到要保存的文档中，这将节省几个字节.

The maximum size of a document is 2 MB and cannot be increased. In your case you can store the image in blob storage and attach the url as a property to the document you are saving which will save few bytes.
