Hi, community Issue: support other business systems to run in DS. https://github.com/apache/dolphinscheduler/issues/16672 Issue background： description present situation: for enterprises that use Apache dolphinscheduler, Apache dolphinscheduler is more often used as the core scheduling system for data processing. however, there are often other business systems in the enterprise, and most of these business systems have requirements such as scheduled task job management. At the same time, the role of the business system may also be applied to a certain aspect of data processing.
planned renovation: add DS-plugin Java plug-in (1) the business system is referenced through Maven. the business system implements fixed interfaces and uses fixed annotations to complete the creation of scheduled task executors. the plug-in includes registration of Apache dolphinscheduler api-server, workflow, node creation, scheduled task creation, etc. core functions. (2) business system application processing can be referenced through the parent-child process, making it a part of data flow. 2.Apache dolphinscheduler api-server and master-server add corresponding processing logic (1) api-server adds registration, task creation processor and logic. (2) master-server adds task triggering and result processing logic (3) add external system nodes the purpose of SDK is to allow third-party systems to register in DS through the integration of DS SDK plugins. the SDK includes third-party system registration, task list functions, task parameter functions, and task execution functions. third party systems can delegate tasks to DS triggers by integrating SDKs and corresponding implementations. for example, in a data quality system, if a company wants to use its own data quality system to implement data quality audit tasks, and the data processing tasks are in DS, the processing tasks of the two platforms cannot be triggered by dependencies. the purpose of this feature is to solve the integration problem between DS and third-party systems. the above introduction is about the modification of DS, including the main process of task definition development and task execution. the main implementation of this DSIP is to provide a dependency (DS SDK) for third-party systems; 2. add a new node (Other System node) to DS the design scheme can be seen in the following figures： [image: image.png]
