How to use this cron schedule
If your query is cron every 1 hour, the correct expression is `0 * * * *`. It runs exactly once each hour at minute zero, which makes schedules easy to communicate and audit. This cadence is common when teams want timely updates without paying the compute cost of every-5-minute jobs. In 2026, it remains a strong baseline for internal reporting, periodic data pulls, and lightweight workflow orchestration where strict real-time latency is not required.
The most important design decision is what happens when a single run fails or runs long. Hourly schedules are frequent enough that silent errors can compound quickly if retries are not defined. Add bounded retry logic, idempotency keys, and completion signals so downstream consumers can trust the data. Keep cron commands short and delegate heavy business logic to versioned scripts or services. That separation makes reviews safer and allows you to test behavior without editing the scheduler itself every time a job changes.
Before promoting to production, validate expected run timestamps in the same timezone used by operators and stakeholders. A reliable process is to simulate several next-run windows, confirm no overlap with backup windows, then release with monitoring enabled from day one. If one-hour cadence becomes too expensive, move specific steps to every two or three hours rather than bloating a single job. This page links to those alternatives so you can tune frequency by workload while preserving predictable scheduling semantics.
