[PowerJob](https://github.com/PowerJob/PowerJob) is an open-source distributed computing and job scheduling framework which allows developers to easily schedule tasks in their own application.
Refer to [Quick Started Tutorial](https://www.yuque.com/powerjob/en/baz8y6) for detailed information.
# Introduction
### Features
- **Friendly UI:** [Front-end](http://try.powerjob.tech/#/welcome) page is provided and developers can manage their task, monitor the status, check the logs online, etc.
- **Abundant Timing Strategies:** Four timing strategies are supported, including CRON expression, fixed rate, fixed delay and OpenAPI.
- **Multiple Execution Mode:** Four execution modes are supported, including stand-alone, broadcast, Map and MapReduce. Distributed computing resource could be utilized in MapReduce mode, try the magic out [here](http://try.powerjob.tech/)!
- **DAG Job Flow Support:** Both job dependency management and data communications between jobs are supported.
- **Cross-language Client Support:** So far, developers can use Java, Spring, Shell, Python to write their own PowerJob client and define tasks that can be triggered by PowerJob workflow.
- **Disaster Tolerance Support:** As long as there are enough computing nodes, configurable retry policies make it possible for your task to be executed and finished successfully.
### Applicable scenes
- Timed tasks, for example, allocating e-coupons on 9 AM every morning.
- Broadcast tasks, for example, broadcasting to the cluster to clear logs.
- MapReduce tasks, for example, speeding up certain job like updating large amounts of data.
- Delayed tasks, for example, processing overdue orders.
- Customized tasks, triggered with [OpenAPI](https://www.yuque.com/powerjob/en/fs3vg0).
