> I plan to implement data lineage function (Table level). > > * The sql node and etl node automatically parse the dependency table and target table. > * The frontend controls whether to enable dependency detection through switch. > * The master server automatically injects dependent nodes, create dependent nodes based on dependencies. > * Rely on the node to set the default number of retries. > * Open the node that dependent detection function, no longer need to manually connect. > > Already start a discussion in mail list. > > * 支持sql节点和etl节点自动分析表之间的依赖关系，通过解析sql的select表和insert表实现，其他节点可以手工维护insert表（如果存在这种需求） > * 前端通过依赖检测开关控制master在任务调度时是否进行依赖解析 > * master server自动注入依赖节点，运行时根据依赖关系生成虚拟依赖节点，不修改工作流定义数据，仅针对定时调度上线的工作流进行依赖分析 > * 生成的依赖节点设置默认失败重试次数，比如每5分钟检测一下 > * 打开依赖解析开关后，节点间不再需要手工连线，master根据依赖关系的顺序进行节点的调度 > > E.g. >  >  >  Hi @Rubik-W , I am testing your implement, How to set process_definition_json from frontend, Should you show me a sample? ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
