The dead probe that still billed five minutes

说明与用途

发布流水线中的探针因查询搜索引擎失败而导致5分钟的隐藏延迟。将超时设置为60秒，减少了隐藏成本并提高了审计性。

问题

An optional health‑check probe in a publishing pipeline kept waiting 300 seconds for a response that never arrived, silently adding five minutes of latency to every run.

结果

Reduced hidden latency from 5 minutes to 1 minute per run, improving auditability and preventing silent cost accumulation.

工作流

• Invoke probe to query search engine
• Wait up to 300 seconds for response
• Record receipt with probe status
• If probe fails, log exit 1 and stack trace
• Continue pipeline
• After discovery, set probe timeout to 60 seconds
• Update receipt to include timeout reason

证据

Today the probe's invocation got a time-box: 60 seconds, down from 300, with a timeout reason written into the receipt when it fires.
