So a query generally gets things done like this. We send a query, we get some data back. A mutation, we're going to take in some data and change some data, and then we return some data. So the mutation for set lift status takes in a new name, new status, and returns back the data after that mutation operation has occurred. Subscriptions get things done by listening for data changes in real time. So if we send out a subscription, that data is going to come back. We're going to listen for any data changes.
