Hello Kafka Community, I'm reaching out for assistance with an issue I've encountered in our Kafka cluster that's been running smoothly for over a year. Our setup includes:
Kafka Version: 3.6.0 Cluster Configuration: 3-node cluster running in KRaft mode (without ZooKeeper). Issue Description: Despite configuring replication for some topics to enhance data redundancy and fault tolerance, AKHQ (our Kafka monitoring tool) indicates that these topics are not replicating as expected. This is puzzling because the cluster otherwise operates normally, and we've been relying on this setup for a significant period. Given the following: The cluster is in KRaft mode, aiming for a simplified architecture. We've specifically added replication to certain topics, expecting this to reflect in AKHQ. Despite our efforts and the cluster's long-term stability, replication issues persist according to AKHQ. I'm wondering if anyone has encountered similar issues or could offer insights into: Potential misconfigurations with topic replication factors or broker settings that could lead to this issue. Any known quirks or bugs with KRaft mode that might affect replication visibility or functionality. Steps for diagnosing and resolving issues related to replication in a KRaft mode cluster, especially regarding tooling compatibility with Kafka 3.6.0. Suggestions for verifying network connectivity between brokers or any ACL/permission settings that might inadvertently prevent proper replication. Any advice, diagnostic tips, or shared experiences with similar setups would be immensely appreciated. I'm particularly interested in ensuring that our replication configurations are effective and accurately monitored, maintaining the high availability and fault tolerance our Kafka cluster is intended to provide. Thank you in advance for your time and assistance! -- Rinaldo DiGiorgio - 410-714-1099 www.nabancard.com North American Bancard, LLC - 250 Stephenson Highway -Troy, MI 48083 CONFIDENTIALITY NOTICE This e-mail message and any attachments are only for the use of the intended recipient and may contain information that is privileged, confidential or exempt from disclosure under applicable law.
