Kafka Partition Skew

A single large tenant's traffic has spiked, and its messages are concentrated on one Kafka partition. Aggregate consumer-group utilization still looks moderate — most consumers are nearly idle — but the one partition that tenant's messages land on is falling critically behind, because only one consumer can ever read from a given partition at a time. Diagnose why the backlog keeps growing despite healthy-looking aggregate metrics, and restore throughput before downstream processing falls critically behind.
