ElasticJob - 分布式作业调度解决方案

官方网站: https://shardingsphere.apache.org/elasticjob/

Stargazers over time

ElasticJob 是一个分布式调度解决方案,由两个相互独立的子项目 ElasticJob Lite 和 ElasticJob Cloud 组成。 它通过弹性调度、资源管控、以及作业治理的功能,打造一个适用于互联网场景的分布式调度解决方案,并通过开放的架构设计,提供多元化的作业生态。 它的各个产品使用统一的作业 API,开发者仅需一次开发,即可随意部署。

ElasticJob 已于 2020 年 5 月 28 日成为 Apache ShardingSphere 的子项目。 欢迎通过邮件列表参与讨论。
