Using NoSQL with MongoDB

You may initially think that Go is better suited to relational databases due to Go structures and because Go is a typed language. When working with something like the github.com/mongodb/mongo-go-driver package, Go can nearly arbitrarily store and retrieve structure objects. If you version your objects, your schema can adapt and it can provide a very flexible development environment.

Some libraries do a better job of hiding or elevating these abstractions. The mongo-go-driver package is an example of a library that does an excellent job of the former. The following recipe will create a connection in a similar way to Redis and MySQL, but will store and retrieve an object without even defining a concrete schema.
