Introduction

Openjob is A distributed and high-performance task scheduling framework that supports multiple cronjob, delay task, workflow, lightweight distributed computing, unlimited horizontal scaling, with high scalability and fault tolerance. Also has permission management, powerful alarm monitoring, and support multiple languages.

• High reliability
  • Distributed with stateless design, using the Master/Worker architecture, supports multiple databases (MySQL/PostgreSQL/Oracle)
• High performance
  • System uses a consistency sharding algorithm, lock-free design, task scheduling is accurate down to the second, supporting lightweight distributed computing and unlimited horizontal scaling
• Cronjob
  • Supports distributed cronjob, fixed rate tasks, high-performance second tasks, and onetime tasks
• Distributed computing
  • Supports multiple distributed programming models such as standalone, broadcast, Map, MapReduce, and sharding, easy to complete distributed computing for big data
• Delay task
  • High performance delay task based on Redis , support multi-level storage, and provides rich statistics and reports
• Workflow
  • Supports workflow scheduling engine, visual DAG design, and easy to complete complex task scheduling
• Permission management
  • User management, supports menu, button, and data permission settings, flexible management of user permissions
• Alarm monitoring
  • Overall monitoring metrics, rich and alarm in time, easy to locate and resolve online problem
• Multiple languages
  • Support multiple languages such as Java, Go, PHP, and Python, as well as build with frameworks such as Spring Boot, Gin, and Swoft
