Cavalcade is a scalable job system designed as a drop-in replacement for the built-in pseudo-cron system in WordPress. It is built for developers and administrators managing high-traffic or multi-site installations where the default task scheduler becomes a bottleneck. The system integrates transparently with existing cron functions, requiring no code changes on the WordPress side.

• Horizontal Scalability: Distributes scheduled jobs across multiple workers, allowing the system to handle increased load by adding more processing resources. This prevents task queues from backing up during traffic spikes.
• Multi-Site Compatibility: Operates effectively within WordPress multi-site networks, managing scheduled tasks across numerous individual sites from a centralized, efficient queue.
• Database-Backed Job Storage: Moves cron jobs into a dedicated database table, separating them from standard WordPress transients. This provides more reliable storage and easier management of pending and completed tasks.
• Daemon-Based Runner: Uses a persistent runner process that continuously monitors for new jobs and manages worker processes. This architecture ensures jobs are executed promptly without relying on page visits to trigger them.
• Transparent Integration: Functions as a complete replacement for the default system while maintaining full compatibility with the wp_schedule_event and related cron APIs, making adoption straightforward.
