Flood-alert producers keep publishing while a slow emergency dashboard consumer falls behind. What ingestion design principle should the city apply?
Select an answer to reveal the explanation.
Short Explanation
If the hose keeps pouring and the bucket lags, you need a plan—not silent leaks. Civic alert buses need clear overflow and back-pressure rules so critical messages are not tossed quietly. Slow consumers deserve policy, not hope.
Full Explanation
When producers outpace consumers, systems experience lag and potential buffer pressure. For public-safety style topics, silently dropping alerts is unacceptable without an explicit retention, throttle, or failover policy. Permanent producer shutdowns and wholesale retreat to nightly files also fail real-time emergency needs. Ingestion design must state how overflow is handled—retain, slow producers, scale consumers, or route with priority—so critical civic signals stay governed.
