Raw Blame History

Quotas, backpressure, and DLQ (NR4)

  • Per-tenant quotas: 500 deliveries/minute default; channel overrides: webhook 200/min, email 120/min, chat 240/min.
  • Burst budget: 2x quota for 60 seconds, then hard clamp.
  • Backpressure: reject enqueue when backlog > quota*10 or DLQ growth > 5%/min.
  • DLQ schema: docs/modules/notify/schemas/dlq-notify.schema.json; redrive requires idempotent delivery_id/dedupe_key.
  • Metrics to alert: backlog depth, DLQ depth, redrive success rate, enqueue reject count.
