How to judge whether a topic is orderly or unordered in RocketMQ?

Question

How to judge whether a topic is orderly or unordered? Can I view it from the RocketMQ-Console? I did not find the relevant documentation.

Answer 1

messages in topic are orderly once rocketmq stored in commit log, like queue. they will behave differently in orderly-consuming and concurrently-consuming(un-orderly).

let's take java for example:

• orderly consuming

• concurrently consuming
