KIP-1103 — Additional metrics for cooperative consumption
Accepted Kafka 4.1 ConsumerMetrics
Adds broker-side Share Group metrics: TotalShareFetchRequestsPerSec, FailedShareFetchRequestsPerSec, TotalShareAcknowledgementRequestsPerSec, and related per-topic and purgatory metrics. Share Group (KIP-932) cooperative consumption had no dedicated broker metrics for share fetch requests, acknowledgements, or Delayed Share Fetch purgatory behavior, preventing observability and performance diagnosis.
