Order Commands Topic
Topic name: order-commands
Description: The purpose for this topic is not other than to store the commands requested from users for creating, updating and cancelling orders for the Order Command component to process these later by implementing the Consume-transform-produce Loop pattern.

Orders Topic
Topic name: orders
Description: This is probably the busiest topic in the overall Reefer Container Shipment reference application. This topic would be the place for any event that has to do with shipping orders. From having events from the Order Command to notify other components of the solution that orders have been created, updated, cancelled and rejected to having events from other components to notify that an order has got a container allocated, a voyage assigned or event that a container has spoilt the fresh goods it is carrying due to an anomaly in the container.
