--------------------------------------
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.
