GitHub user Jason918 added a comment to the discussion: How can i wait consumer to deliver the message with same key
Seems like you are talking about the consumption order guarantee. If you are using a partitioned topic and did not change the producer's message routing mode, ' RoundRobinPartition` by default, make sure messages with the same key go into the same partition. On the consumer end, as long as you don't use the `SubscriptionType.Shared`, the consumption order should be guaranteed.
