Normal messages are messages that have no special features in Message Queue for Apache RocketMQ. They are different from featured messages, such as scheduled messages, delayed messages, ordered messages, and transactional messages.
Note When you use Message Queue for Apache RocketMQ SDK to send and subscribe to messages, note that a topic for one type of message
cannot be used to send or subscribe to another type of message. For example, a topic
for normal messages can be used only to send and subscribe to normal messages. Similarly,
a topic for transactional messages can be used only to send and subscribe to transactional
messages.
