Hi,
RoutingKey are different design with the MessageKey in RocketMQ. MessageKey didn’t have the ability of sharding, it is just used for the indexing query for your special business case, you can use MessageQueueSelector for this purpose in RocketMQ. While some other properties in AMQP, you could use MessageConst to map and do some work when fill with them. In consumer, you could use the tag to simulate the exchange semantic.
