- Have you ever felt helpless when batches of business tasks require handling?
- Have you ever felt depressed about tasks that carry with complex dependencies?

# Introduction
### Features
- Simple to use: PowerJob provides a friendly front-end Web that allows developers to visually manage tasks (Create, Read, Update and Delete), monitor task status, and view operation logs online.

- Complete timing strategy: PowerJob supports four different scheduling strategies, including CRON expression, fixed frequency timing, fixed delay timing as well as the Open API.
- Various execution modes: PowerJob supports four execution modes: stand-alone, broadcast, Map, and MapReduce. It's worth mentioning the Map and MapReduce modes. With the completion of several lines of codes, developers could take full advantage of PowerJob's distributed computing ability.
- Complete workflow support. PowerJob supports DAG(Directed acyclic graph) based online task configuration. Developers could arrange tasks on the console, while data could be transferred between tasks on the flow.

- Complete workflow support. PowerJob supports DAG(Directed acyclic graph) based online task configuration. Developers could arrange tasks on the console, while data could be transferred among tasks on the flow.
- Extensive executor support: PowerJob supports multiple processors, including Spring Beans, ordinary Java objects, Shell, Python and so on.
- Simple in dependency: PowerJob aims to be simple in dependency. The only dependency is merely database (MySQL / Oracle / MS SQLServer ...), with MongoDB being the extra dependency for storing huge online logs.
- High availability and performance: Unlike traditional job-scheduling frameworks which rely on database locks, PowerJob server is lock-free when scheduling. PowerJob supports unlimited horizontal expansion. It's easy to achieve high availability and performance just by deploying as many PowerJob server instances as you need.

- Quick failover and recovery support: Whenever any task failed, PowerJob server would retry according to the configured strategy. As long as there were enough nodes in the cluster, the failed tasks could execute successfully finally.
- Convenient to run and maintain: PowerJob supports online logging. Logs generated by the worker would be transferred and displayed on the console instantly, therefore reducing the cost of debugging and improving the efficiency for developers significantly.

### Applicable scene
### Applicable scenes
- Scenarios with timed tasks: such as full synchronization of data at midnight, generating business reports at desired time.
- Scenarios that require all machines to run tasks simultaneously: such as log cleanup.
- Scenarios that require distributed processing: For example, a large amount of data requires updating, while the stand-alone execution takes quite a lot of time. The Map/MapReduce mode could be applied while the workers would join the cluster for PowerJob server to dispatch, to speed up the time-consuming process, therefore improving the computing ablility of whole cluster.

- Scenarios with delayed tasks: For instance, disposal of overdue orders.

### Design goals
PowerJob aims to be an enterprise scheduling middleware. By deploying PowerJob-server as the scheduling center,
all the applications could gain scheduling and distributed computing ability relying on PowerJob-worker.
