Our ad generation service was dropping requests left and right during busy hours. Load tests showed the Postgres connection pool maxing out, and failed jobs climbed to one in every ten requests. Each failure meant a retry loop that ate CPU and left users staring at error screens.
We swapped the default connection handling for a tuned pooler with strict timeouts and a small retry queue backed by Postgres itself. No new frameworks, no flashy orchestration layer—just better connection limits and a dead-letter table for the jobs that still failed after three attempts.
Failures dropped from 10 % to under 1 %. That single change gave us ten times the effective reliability without adding servers. The extra headroom let the scroll-stopping ad maker handle real traffic spikes without constant alerts.
Same codebase, same hardware, just less noise in the logs and fewer 3 a.m. pages.
