You can leverage the ExportZkOffsets/ImportZkOffsets tools to do this.
ExportZkOffsets exports the consumer offsets for your group to a file in a
certain format. You can then place the desired offset per partition you
want to reset your consumer to in the exported file.
1. Shutdown the consumer
2. Export current offsets
3. Get the desired offset (current offset - 10K). As David mentions, this
is approximate and might get you more than 10K messages if the data is
4. Replace the exported offsets with these offsets
5. Restart the consumer.
