schedules

To automate scripts on a cron schedule using Windmill, create a YAML schedule file named with the `.schedule.yaml` suffix containing your cron expression, script path, timezone, and enabled flag, then deploy it with the Windmill CLI.

A Windmill schedule YAML file requires the schedule, script_path, timezone, is_flow, and enabled fields. You can optionally include retry, on_failure, and on_recovery settings to handle errors and ensure robust operation.

Yes, you can schedule Windmill flows by setting the `is_flow` field to true in your YAML schedule file and providing the target flow path in the `script_path` field.

Handle failures and retries for automated cron jobs by configuring the optional retry, on_failure, on_recovery, and on_success settings within your YAML schedule file to manage error handling and recovery logic.

Windmill supports precise cron expressions for recurring tasks by allowing 6-field cron syntax that includes seconds, enabling exact timing for nightly data processing, batch jobs, and maintenance tasks.

The best way to run nightly data processing across multiple projects is using a structured cron-based schedule mechanism with YAML files to map paths to tasks, eliminating manual triggering overhead.
