Workflow Overview
Automated workflow for Airflow that manages DAG runs with 12 nodes. It allows manual triggering, monitors the state of DAG runs, and handles errors effectively. The workflow waits for specified durations and counts attempts, ensuring timely execution and providing clear feedback on success or failure, enhancing operational efficiency.
This workflow is ideal for:
- Data Engineers who need to automate the triggering of Airflow DAGs and monitor their states.
- DevOps Teams looking for a robust solution to integrate Airflow with other systems while handling errors effectively.
- Business Analysts who require timely execution and monitoring of data workflows and want to ensure that processes are running smoothly.
- Project Managers overseeing data pipeline projects that require manual triggers and need to ensure that tasks are executed without delays.
This workflow addresses the challenge of managing Airflow DAG runs by:
- Automating the Triggering of DAGs based on user input, thus reducing manual overhead.
- Monitoring the State of DAG runs to ensure they are progressing correctly and handling failures gracefully.
- Implementing Wait Logic that allows for retries if a DAG run is queued for too long, ensuring timely execution.
- Providing Error Handling through StopAndError nodes, which helps in identifying and managing failures effectively.
The workflow consists of the following key steps:
- Triggering the Workflow: The workflow starts with a manual trigger, receiving input parameters such as
dag_id,task_id,conf,wait, andwait_time. - Setting Up API Configuration: It sets the base URL for the Airflow API for subsequent API calls.
- Initiating DAG Run: A POST request is made to the Airflow API to trigger the specified DAG with the provided configuration.
- Checking DAG Run State: The workflow periodically checks the state of the DAG run to determine if it is in a
queued,running, orfailedstate. - Handling State Conditions: Based on the state of the DAG run, the workflow either waits, increments a count, or stops with an error message if the run fails.
- Implementing Wait Logic: If the DAG run is queued, the workflow waits for a specified amount of time before checking the state again.
- Final Result Retrieval: Once the DAG run is complete, the workflow retrieves the result of the task from Airflow's XCom entries.
