# Pipelines

Pipelines help us run the tasks in a directed orderly fashion. Currently we support linear async pipeline, with plans to release async DAG pipelines in next versions.

Currently out of the box we support 1 Pipeline

1. **LinearAsyncPipeline**

Linear async pipeline runs the tasks one after another in sequence. For example
If there are three tasks A, B, C. Then using the LinearAsyncPipeline class you can run the tasks
in the fashion A→B→C.

```python theme={null}
from lyzr_automata.pipelines.linear_sync_pipeline import LinearSyncPipeline

LinearSyncPipeline(
    name="pipeline name",
		# completion message after pipeline completes
    completion_message="pipeline completed",
    tasks=[
				# tasks are instance of Task class
        task_a, # Task A
        task_b, # Task B
				task_c  # Task C
    ],
).run()
```

**Dependency input tasks flow**

1. If any task depends on multiple inputs which come from any previous task they can be provided in the input\_tasks param of the task instance.

<Note>
  Note: providing explicit input\_tasks to a task instance means it will rely solely on those tasks for its output, without considering the sequence output of previous tasks at that point. However, the output from the current task will still be processed further.
</Note>

**Example**

Task A → Task B → Task C → TASK D

if Task D requires output of Task A and Task C then, TASK D input\_tasks param will have list of instance of Task class which will be task A and task C instances.
