Cavalcade is a job scheduling system for WordPress, designed to replace the built-in wp-cron. It addresses the limitations of wp-cron, particularly its reliability and scalability, by introducing a daemon process (the runner) and worker processes for task execution. Cavalcade stores scheduled tasks in a dedicated database table and utilizes WP-CLI to run them. This setup enhances the robustness and performance of scheduled WordPress tasks.
Cavalcade offers a drop-in replacement for wp-cron with no code changes required in the WordPress site itself. Its design allows for horizontal scaling by adding more worker processes to handle increasing task loads. The system's robust architecture ensures task reliability even under heavy load, making it suitable for high-traffic WordPress sites.
- Scalability: Handles a large number of scheduled tasks and high traffic volumes efficiently.
- Multisite Support: Works seamlessly with WordPress multisite installations.
- WP-CLI Integration: Executes tasks using WP-CLI for flexible command execution.
- Daemon Process: A background process manages job scheduling and worker distribution.
- Database Storage: Stores scheduled tasks in a dedicated database table for persistence.
- Extensible: Plugins allow for extending Cavalcade's functionality and integrations.
- Worker Management: The system automatically manages a pool of worker processes.
Cavalcade is an actively maintained project with a proven track record of use on high-traffic sites. Recent commits and issue activity indicate ongoing development and support. Comprehensive documentation and a growing community suggest a stable and reliable system. The project has been successfully deployed at scale for several prominent WordPress sites.
