Hi Andrew, Thanks for the nice KIP, This KIP design for introducing dead-letter queues (DLQs) for Share Groups is generally clear and reasonable, addressing the key pain points of handling "poison message". D01: Should we consider implementing independent ACL configurations for DLQs? This woul

hi Fede Thanks for this KIP I think JMX Prometheus Exporter is the most popular choice these days, as it integrates well with modern monitoring stacks (Prometheus + Grafana). A similar alternative could be Jolokia + Hawtio, but I haven't seen this stack used much with Kafka. In both cases, a Jav

Hi Fede (and Kirk), Thanks for the KIP. A comment on Kirk's comment :) KT01: This is certainly an interesting question. I think we need a small KIP for kafka-console-consumer.sh because it only supports Consumer.subscribe(Pattern), and not the newer KIP-848 Consumer.subscribe(SubscriptionPattern)

Re: [DISCUSS] KIP-1192: Add include argument to ConsumerPerformance tool

Hi Kirk and Andrew. Thanks so much for the feedback. I agree that consistency is better for now, but once this is done, I can follow up with adding SubscriptionPattern support to both ConsumerPerformance and ConsoleConsumer tools (I guess a KIP is not needed in this case). On Tue, Jul 15, 2025 at
