Every 10 Seconds

Use in your stack

{
  "schedule": {
    "cron": "0/10 * * * * ?",
    "timezone": "UTC"
  }
}

// 6-field: second minute hour day-of-month month day-of-week
@Scheduled(cron = "*/10 * * * * *")
public void everyTenSeconds() {
    // ...
}

// Simpler for pure intervals:
@Scheduled(fixedRate = 10000) // milliseconds
public void everyTenSecondsFixedRate() {
    // ...
}

Variations

Common use cases

• Polling a job queue or webhook backlog on a tight loop.
• Refreshing a near-real-time cache or leaderboard.
• Sampling a sensor or metric at 6× per minute.
• Retrying a flaky downstream call at a short, fixed cadence.

Gotchas

• **Unix crontab cannot do this.** The 5-field format has no seconds field; its minimum interval is one minute. Kubernetes CronJob and GitHub Actions share that limit.
• In Spring, `*/10 * * * * *` is the 6-field form (seconds first) — not to be confused with Unix's `*/10 * * * *`, which means every 10 *minutes*.
• In Quartz, use `0/10 * * * * ?` — `0/10` in the seconds field means "from second 0, every 10 seconds," and `?` fills the unused day-of-week field.
• For a fixed interval like this, `@Scheduled(fixedRate = 10000)` (Spring) or `tokio::time::interval` (Rust) is usually simpler than a cron expression.
• Watch for overlap: if a run can exceed 10 seconds, use `fixedDelay` or an in-flight guard so invocations don't stack.
