DynamoDB

What is it?

A cloud NoSQL database (very different from normal SQL databases; it's more like a key-value store than a relational database).

Why did we choose it?

It's useful for storing information we need for some services to work together, where storing the information in the main database won't work because of how the network infrastructure is set up.

What do we use it for?

When a user requests a copy of their Deserted Chateau data, we have a DynamoDB table which records which data requests are ready to be emailed.
