一、版本问题
原Activiti的Tijs Rademakers团队去开发Flowable框架。
现Activiti7是 Salaboy团队开发的,内核使用的还是Activiti6,扩展了云化。Activiti5、Activiti6代码目前由 Salaboy团队代为维护,目前官宣已经暂停维护
Activiti:Activiti在目前来看有点不思进取,核心功能和内核的优化并没有太大进步,着力点全在商业版和云上面,核心只支持BPMN2协议,跟6版本没有什么区别。如果你是一个老的Activiti使用者,并且只是用BPMN2协议,可以选用Activiti(非Cloud版本)。
Flowable:Flowable不管是功能层面还是在代码层面来讲,都是这3个中最重的,当初跟Activiti分道扬镳的原因也是因为理念不一样,Flowable更注重其功能性、扩展性和性能。在上面表格中,历史异步归档和异步任务全局锁都是对性能的极大优化,特别是异步任务这一项,当年在使用Activiti的使用是一个极大的困扰,因为异步任务的吞吐反而会随着实例数的增加而加速恶化。Flowable比较臃肿,它支持了太多的东西,以致于如果想做POC或者Demo,环境搭建这一步都够呛。但是如果你本身就想做一个扩展性强的,性能高的工作流平台(SaaS\PaaS),Flowable是不二的选择。
Camunda:Camunda是这3个里面比较轻量的一个,但是它并没有去掉PVM这个性能较差的流程推动引擎,所以如果你对性能要求很高的话,PVM肯定是不能满足的(Activiti已经在6.X版本的时候放弃了PVM,Flowable亦是如此)。但是Camunda有一个好东西就是它的编辑器,它是基于http://bpmn.io的bpmn.js,cmmn.js,dmn.js来开发的,并且开源了自己的组件库,所以,如果你想做一个轻巧的、灵活的、定制性强的编辑器,工作流是嵌入式的,那么Camunda是一个好选择。
