Investigation and Resolution of CPU Spike in a Kafka-Go Consumer Using pprof

Using Go’s pprof, the team traced a gradual CPU spike in a high‑throughput kafka‑go consumer to a saturated commit queue and repeatedly nested context values, which forced costly lookups; eliminating the unnecessary trace‑id context injection (or recreating a fresh context each loop) resolved the issue and reduced CPU usage to under 2 %.
