Why use this schedule
The fastest schedule most cron systems allow. It suits near-real-time polling where waiting five minutes is too slow.
- Polling a queue or an inbox for new work
- Heartbeat pings to an uptime monitor
- Flushing a small in-memory buffer to disk

Things to watch out for in Google Cloud Scheduler
- Cloud Scheduler uses unix-cron, so */15 runs every 15 minutes at :00, :15, :30 and :45.
- Cloud Scheduler takes any tz database zone (default UTC) and runs on wall-clock time, so daylight saving can make jobs run or not run unexpectedly. Google recommends UTC to avoid that.
The common mistake with this schedule
A job that takes longer than one minute will overlap with the next run. Guard against it with a lock, Quartz @DisallowConcurrentExecution, or concurrencyPolicy: Forbid in Kubernetes.
