Background Scheduler

A centralized scheduler runs cron and interval jobs reliably across services by enforcing a singleton pattern to prevent duplicate runners. It manages periodic tasks like ETL pipelines and health checks with timezone awareness and execution history.

Duplicate interval job execution occurs when multiple scheduler instances run concurrently. A singleton pattern enforces a single runner instance, preventing duplicate task execution and ensuring centralized cron job scheduling remains reliable.

Timezone-aware scheduling for maintenance tasks is supported natively. You can configure timezones directly when registering cron triggers, ensuring scheduled ETL pipelines and health checks execute at the correct local times.

The best way to log execution history for scheduled batch processing is using a centralized scheduler with built-in logging. It records an execution history for auditability, allowing you to configure history length and log level.

APScheduler supports singleton enforcement for periodic ETL pipelines through this centralized scheduler. It applies a singleton pattern to avoid duplicate runners, ensuring your cron-based triggers and interval jobs execute only once per scheduled cycle.

To set up a daily health check, instantiate the background scheduler and register a cron trigger for your task function at the desired time, such as daily at 00:00. The scheduler handles execution, logging, and history tracking automatically.
