Reprocess messages

Reprocess Kafka messages in Conduktor Console: replay records from a topic offset to republish or recover data without custom code.

Overview

Conduktor Console can help you reprocess messages within a topic.

This could be used for reprocessing messages from an existing DLQ or for pushing messages into another topic.

Select a message to reprocess and a new target topic

In Console, go to Topics and open the message you want to reprocess. You can start from either location:

• In the consumed-message drawer, click Reprocess in the header.
• Click Share to open the message’s standalone page, then click Reprocess in the toolbar.

Messages at offset 0 can’t currently be reprocessed from Console.

In the next page, select the target topic that you want to publish the message to.

Here, we want to reprocess the message in the customers topic.

Edit and process the message

The previous step leads us to the Produce page of the target topic, with an auto-populated form containing our record. From there, we can easily modify its key, value and headers.

When you’re ready, you can press the Produce button and you will see your record being produced. Go to the Consume page of this topic in order to retrieve your reprocessed record.
