Hi all, This email starts the discussion thread for KIP-1257: Partition Size Percentage Metrics for Storage Monitoring. This KIP introduces retention-aware, percentage-based partition metrics that significantly improve Kafka’s storage observability. The proposed metrics simplify alerting, enhance capacity planning, and provide clear visibility into retention pressure—especially for tiered storage—while remaining lightweight, backward compatible, and operationally intuitive.
I'd appreciate your initial thoughts and feedback on the proposal. https://cwiki.apache.org/confluence/x/MAEXG Thanks, Manan
