When a message cannot be processed, we are placing the message on a dead-letter topic. We now have several hundred messages on the dead-letter topic that were placed there due to a bug in our application. Now that we have fixed the causing bug, what is the easiest way to "move" all messages from the dead-letter topic back to the normal topic to be reprocessed?
In RabbitMQ, you would just move the messages via the RabbitMQ dashboard; is there an equivalent in kafka, or do you need to code a separate application to move the messages?
