KIP-977 — Partition-level Throughput Metrics
Accepted MetricsBroker
Adds per-partition metrics for `MessagesInPerSec`, `BytesInPerSec`, and `BytesOutPerSec` alongside existing topic-level metrics. Topic-level throughput metrics cannot reveal partition hot-spots, making it impossible to detect key skew or diagnose which specific partition is causing ISR shrinkage or broker overload.
