Audio N/AQuick interview answer
On-call for Kafka Exactly-Once Semantics: alert on lag/latency, error spikes, and saturation — with runbooks. Baseline: Idempotent producer + transactional writes (read-process-write in one transaction) give EOS within Kafka. End-to-end EOS needs idempotent sinks or outbox pattern.
Detailed answer
On-call monitoring for Kafka Exactly-Once Semantics: • Golden signals: latency, traffic, errors, saturation • Kafka Exactly-Once Semantics-specific gauges (queue delay, pool wait, cache miss, etc.) • Alerting: burn-rate / multi-window so pages are actionable • Runbook: mitigate → diagnose → escalate Parent context: Baseline: Idempotent producer + transactional writes (read-process-write in one transaction) give EOS within Kafka. End-to-end EOS needs idempotent sinks or outbox pattern.
Full explanation
Tie each alert to a user-visible or SLO impact for Kafka Exactly-Once Semantics. Baseline: Idempotent producer + transactional writes (read-process-write in one transaction) give EOS within Kafka. End-to-end EOS needs idempotent sinks or outbox pattern.
