Dag
type: "io.kestra.plugin.core.flow.Dag"
Create a directed acyclic graph (DAG) of tasks without explicitly specifying the order in which the tasks need to run.
List your tasks and their dependencies, and Kestra will figure out the execution sequence. Each task can only depend on other tasks from the DAG task. For technical reasons, low-code interaction via UI forms is disabled for now when using this task.
Examples
Run a series of tasks for which the execution order is defined by their upstream dependencies.

Properties
concurrent
- Type: integer
- Dynamic: ❌
- Required: ✔️
- Default:
0
Number of concurrent parallel tasks that can be running at any point in time.
If the value is
0
, no concurrency limit exists for the tasks in a DAG and all tasks that can run in parallel will start at the same time.
