Do you think it's a good idea to save billions of images into Database?

Question

Recently, I and my colleagues, we are discussing how to build a huge storage systems which could store billions a pictures which could searched and download quickly.

Answer 1

When dealing with binary objects, follow a document centric approach for architecture, and not store documents like pdf's and images in the database, you will eventually have to refactor it out when you start seeing all kinds of performance issues with your database. Just store the file on the file system and have the path inside a table of your databse. There is also a physical limitation on the size of the data type that you will use to serialize and save it in the database. Just store it on the file system and access it.
