You can configure default Params in your DAG code and supply additional Params, or overwrite Param values, at runtime when you trigger a DAG. Param values are validated with JSON Schema. For scheduled DAG runs, default Param values are used. DAG Runs. A DAG Run is an object representing an instantiation of the DAG in time. Any time the DAG is executed, a DAG Run is created and all tasks inside it are executed. The status of the DAG Run depends on the tasks states. Each DAG Run is run separately from one another, meaning that you can have many runs of a DAG …Platform created by the community to programmatically author, schedule and monitor workflows.Configuration Reference.
