You are looking at the 1.4 version of Karafka that is no longer supported.

Karafka 1.4 is no longer supported and contains critical errors, included but not limited to:

• Double processing of messages
• Skipping messages
• Hanging during processing
• Unexpectedly stopping message processing

To resolve these issues, it is highly recommended to upgrade to Karafka 2.1 or higher.
