#### Framed protocols

Framed protocols like http/2 don't lend themselves to blocking APIs. Each application-layer thread wants to do blocking I/O for a specific stream, but the streams are multiplexed on the socket. You can't just talk to the socket, you need to cooperate with the other application-layer threads that you're sharing it with.

When you access `my_user.items`, SQLAlchemy will actually go and fetch the items from the database in the `items` table and populate them here.
