Hello Team, During tiered storage performance testing on Kafka 3.9.1, we observed cases where a broker did not trigger scheduled RLMCopy tasks, resulting in no segment uploads to remote storage. Scenarios observed: - During a rolling restart while tiered storage was actively copying segments, one broker (out of six) stopped copying segments after restart. - After multiple rolling restarts before enabling tiered storage at topic level, enabling tiered storage again caused one broker (out of six) to stop copying segments. In both cases, restarting the affected broker resolved the issue and copying resumed. DEBUG logging showed that RLMCopy tasks were created for leader partitions, traffic was active, and rolled segments were available. However, no debug logs appeared from the actual copy path < https://github.com/apache/kafka/blob/3.9/core/src/main/java/kafka/log/remote/RemoteLogManager.java#L839 >, suggesting the copy workflow was not being tri...

Hello Team, Can you please confirm this pattern, that when we get any vulnerability of jetty and fix from Jetty is available, how soon Kafka release a new version with this Jetty?

Hi, I have run our Strimzi test container tests on AArch64, along with unit and integration tests, and verified the checksums. Everything seems to work without any issues. +1 (non-binding). Cheers, Maros

Thanks Sean, I really enjoyed this track last year. I've been thinking about the idea of "streaming AI" for a while now and have a "thought experiment" on using GenAI for Kafka content based delivery here: https://www.linkedin.com/pulse/can-llms-work-streaming-data-paul-brebner-yiflc/ I've also wondered about using Kafka for the a2a protocol? Any thoughts from anyone else on potential use cases for Kafka + GenAI?

Hello, The Call For Papers is now open for the Apache Software Foundation's Community Over Code conference this October in Glasgow. There is a track on "AI Plumbing" at the conference that may be of interest to recipients of this email. Though it doesn't need to be the plumbing focus, I think that a lot can be said about agentic AI. Agentic AI has gotten a lot of buzz in the AI world, and one of the most important things in making agents useful is throwing them together with some good plumbing, e.g. linear or graph-based workflows, orchestration tactics, -communication- protocols, memory, knowledge graphs, etc. There is a lot to talk about. This track might be a perfect place to present efforts in the area, display some work, and perhaps hold a general discussion on experience. Again, Agentic AI is not the focus. Anything regarding putting together any type of AI workflows will be considered relevant. Please forward this email to anybody you know th...
