DocumentDB relatively simple use case is the ability to manage documents via a MongoDB API. Documents can include media, PDFs, and office documents. The metadata is in JSON format for indexing and searching. AWS manages the underlying service and infrastructure.
I’m not a big database guy. I have to be honest, when I here someone say NoSQL, I don’t always remember the qualities and advantages of a relational DB and a non-relational DB. In researching today’s AWS Every Day post, I came across this excellent AWS re:Invent session that talked about the differences between relational DB and other various non-relational DB options.
