##Elastic-Job - distributed scheduled job solution
Elastic-Job is a distributed scheduled job solution. Elastic-Job is composited from 2 independent sub projects: Elastic-Job-Lite and Elastic-Job-Cloud.
Elastic-Job-Lite is a centre-less solution, use lightweight jar to coordinate distributed jobs. Elastic-Job-Cloud is a Mesos framework which use Mesos + Docker to manage and isolate resources and processes.
Elastic-Job-Lite and Elastic-Job-Cloud provide unified API. Developers only need develop code one time, then decide to deploy Lite or Cloud as you want.
- Distributed schedule job coordinate
- Elastic scale in and scale out supported
- Failover
- Misfired jobs refire
- Sharding consistently, same sharding item for a job only one running instance
- Parallel scheduling supported
- Job lifecycle operation
- Lavish job types
- Spring integrated and namespace supported
- Web console
- All features for Elastic-Job-Lite included
- Resources allocated elastically
- Application distribute automatically
- Docker based processes isolation supported (TBD)
- Maven assembly plugin supported
