<p> 工作流调度系统在大数据平台中是一个核心的基础设施,是大数据开发必不可少的重要组成部分。由于数据处理流程常常具有很长的依赖链条,因此依赖单机的crontab等单纯依赖时间调度的方式,往往存在很大的弊端,如依赖不清晰,出错难以查找等问题。因此,我们调研了市面上流行的调度系统。

|
|
|
并和azkaban、airflow做了一些对比:</p>

<p>EasyScheduler由在工作流调度方面工作多年的几位小伙伴研发而成,致力于成为大数据平台的中流砥柱,使调度变得更加容易,更可以从其中文名“易调度”看出我们的初衷,如果你对目前市面上的调度不够满意,非常欢迎试用易调度,欢迎大家加入进来,提出需求,也欢迎贡献代码, 感兴趣的伙伴们可以加我们微信:510570367,一起加入EasyScheduler吧,多多交流!</p>
