Q1 : Topic Existence in Destination Cluster

Ans: MSK Replicator will not create a new topic if a topic with the same name already exists in the destination cluster. Instead, it will utilize the existing topic for replication purposes. This behavior ensures that there's no accidental overwriting of data or disruption to existing consumers.

Q2: Topic Deletion on Replicator Removal

Ans: When you delete an MSK Replicator, it does not automatically delete the topic on the destination cluster. The topic remains intact, even after the replicator is removed. This allows you to maintain data history or potentially use the topic for other purposes.
