khadgarmage edited a comment on issue #201: Task plug-in research, out of solution（任务插件化调研，出解决方案） URL: https://github.com/apache/incubator-dolphinscheduler/issues/201#issuecomment-545028146 @gaojun2048 +1, I agree with your design. I also think of a few additional points here: 1. Task plug-in development, there are two points to consider, one is a plug-in that allows users to directly develop their own business needs, and the use is more flexible; the other is to allow open source enthusiasts to develop third-party plug-ins, so that will promote the development of dolphinscheduler, ideas are more divergent, is there a plug-in market? Therefore, based on the function of the custom task plug-in, it is necessary to support the third-party plug-in import. After the import and the custom task plug-in is a process, the workload itself is not large, but the import is added on the basis of the original. 2. Plug-in development does not depend on java, can be any language, executable program, the scheduling platform does is transparent transmission parameters, execution and scheduling. Developers can have more choices. For example, a shell script can be packaged into a plugin using some parameters. For example， someone can write an executable file in golang, define some parameters, to make a plugin. 3. System upgrade or migration is also a point to note, to ensure that the plug-in will still take effect after migration or upgrade. ----- @gaojun2048 +1 很赞同你的需求，我这边还想到几个补充的点： 1、任务插件化开发，可以有两点考虑，一个是让使用者直接可以开发自己业务需求的插件，使用上更加灵活；另一个是可以让开源爱好者开发第三方插件，这样对ds更是一种正向的推动，思路更发散点，是不是可以有插件market。 所以在自定义任务插件的功能基础上，要支持第三方插件导入，导入后和自定义任务插件是一个流程，这个工作量本身并不大，只是在原来的基础上增加了导入。 2、自定义任务插件，可以不局限于jar包，可以是shell, python, 也可以是一个可执行文件，可以有更多的选择。比如说一个shell脚本使用一些参数，就可以封装成一个插件；同时也可以用golang写一个可执行文件，传到服务器，定义一些入参，也可以作为一个插件。 3、系统升级或者迁移也是个要注意的点，要保证迁移或者升级后，插件依然能够生效。
