Visual Crossing usage limitation
The Visual Crossing API has limits on how much data you can access for free and the real weather only changes in real-time (this means slowly).
The free Visual Crossing account is limited to 1000 records per day so in order to prevent your account from being rate limited, the connector is coded to consume data every 2 minutes, however, you can trigger collection of new data by restarting the service as needed. You will do this several times throughout this tutorial.
Summary
At this stage you have two services running.
One is publishing New York CitiBike data to a topic called bikes-topic and another is publishing Visual Crossing weather data to a topic called weather-topic.
