Event Processing Backpressure

Upstream event producers have surged well past the processing layer's normal drain capacity, and Kafka consumer lag is climbing along with how stale events are by the time they're processed. The database connection pool and the external API's call budget are both shared with other production traffic, and the external API enforces its own rate limits — exceeding them degrades the dependency for longer than the surge itself lasts. Diagnose why the backlog is growing and bring ingestion, processing, and both downstream dependencies back into a durable, sustainable balance.
