Consider this simplified event processing code snippet in a microservice:

eventQueue = []

function processEvent(event) {
  if (event.type === 'update') {
    database.update(event.data)
  }
}

// Events arrive asynchronously
processEvent({type: 'update', data: {id: 1, value: 'A'}})
processEvent({type: 'update', data: {id: 1, value: 'B'}})

// What is the likely final value in the database for id 1?
