使用Flask框架从MongoDB提供文件

I am new in web development with python and flask and mongodb database. What I see is that everybody advises to use Apache to serve files because it's more efficient. But what if I store all my files in MongoDB using GridFS? In this case I do not serve my files by Apache anymore but directly by flask, is it the wrong thing to do?
