             Summary: Support hex-encoded key/value in console consumer and producer
                 Key: KAFKA-21245
                 URL: https://issues.apache.org/jira/browse/KAFKA-21245
             Project: Kafka
          Issue Type: Improvement
            Reporter: Chia-Ping Tsai
            Assignee: Chia-Ping Tsai


I was testing compacted topics and noticed that there is no official tool to write a tombstone for a specific record. The console producer can produce null values (KIP-810), but there is no way to type a binary key, so records with serialized keys (long, Avro, Protobuf, etc.) cannot be deleted from the command line.

Of course, we can leverage AI to generate 1000 tools immediately, but “this tool” can be addressed by supporting hex 🙂

Also, hex is the baseline for all types of records. It is line-safe, so the output can be piped through grep, awk, and other console tools, and it can be fed back into the console producer to reproduce the exact same bytes.
