You may work on your operational processes and try to raise efficiency through workload automation. Sometimes, however, the solutions can backfire, especially when you must manage data pipelines. Automation is highly technical and advanced, so you need to go about it with caution.
When you automate your processes, you have to create data pipelines. Sometimes it becomes hectic, time-consuming and challenging to manage these pipelines. A pipeline may fail to run its scheduled tasks, show errors in the tasks, or not perform some tasks as you expect.
Then you end up checking the pipelines all the time, trying to fix issues and watching the tasks. That defeats the purpose of automation. You may even wonder why you used automation at all, and think it would have been better to do the task manually.
But you don’t need to get worked up like that, especially when you can use smart solutions like the Apache Airflow tool. Here is how it helps you manage data pipelines without the struggle.
How Does Apache Airflow Help You Manage Data Pipelines?
Apache Airflow is a smart workflow management solution. It helps you manage your regular business operations, jobs and tasks. It’s an open-source scheduler. With it, you can create robust data pipelines to schedule, organize, run, monitor and manage all your workflows.
Other schedulers do that too, so what makes Apache Airflow a better solution? The answer is its more advanced features. With Apache Airflow, you can orchestrate multiple data pipelines at the same time. You can also make sure that they don’t fail or perform below expectations.
The tool also lets you set frequency, triggers, rescheduling and retrying for scheduled tasks and jobs. This makes workflow management a breeze. It also removes the struggle to manage data pipelines.
This article explains every benefit that makes Apache Airflow an ideal tool for efficient job scheduling and operations. However, before you can understand those benefits, you need to know the architecture of the tool. So, let’s talk about that first. If you need help building such platforms, see our custom software services. You can also visit the Apache Airflow website.
Apache Airflow Architecture – How It Works?
Apache Airflow works with DAG pipelines. These are Directed Acyclic Graphs that represent the workflows you need to run. The pipelines split into nodes, and each node represents a particular task to run within the DAG.
The user can set the frequency at which tasks run. If tasks depend on certain triggers, the user can set those in the DAGs as well. The tool creates and runs these DAGs efficiently because all its core components stay in sync.
Core Components of Apache Airflow Tool
Apache Airflow has four core components: a front-end, a backend, a scheduler and an executor. These components work in tandem. As a result, you get strong automation with better scheduled, automated and managed jobs and tasks.
Scheduler
This is where you schedule all the tasks. When you create a DAG, the scheduler finds it and queues it for execution. It also checks how the DAGs perform and notices a failed DAG. If you have enabled retry in the DAG, it reschedules the DAG automatically. So, all your tasks are queued, and your data pipelines run at their best.
Front-end
A webserver is the front-end of Apache Airflow. It works as a UI where you can monitor the DAGs and note their status. You can also use this front-end to see the task logs. You can enable, disable or retry scheduled DAGs and monitor them to keep performance efficient.
Executor
The executor runs the tasks and workflows that the scheduler queues. It decides how many tasks the tool can run at the same time. That also depends on the executor’s choice of worker for the DAG. The executor also reads the tasks constantly and updates their status in the logs.
However, you need to be careful with the executor. By default, it uses SerialExecutor, which runs only one task at a time. That’s not advisable at all, because running tasks one by one can delay the processes. So, you must look through the default settings and change them to match your business needs.
Backend
The backend supports the smooth running of the tool. The code is Python-based, which makes it easier for you to start using Apache Airflow. The tool uses MySQL or PostgreSQL to store configuration and other data. For setup and running, the tool has SQLite as the backend, so you need no extra setup.
However, this backend can be risky because there’s a high chance of data loss. It will take you some time to set up the tool with another backend. Still, it’s in your favour, and the setup time is worth it.
So, this was a short introduction to Apache Airflow and how it works. Now you know that it’s a great workflow management solution. It can overcome the challenges you may have faced when you manage data pipelines. Apache Airflow makes automation a breeze, and that’s what makes it a great solution. Here are some more points on why it’s perfect for removing the struggle of maintaining data pipelines.
How is Apache Airflow Tool the Ideal Solution?
Apache Airflow is the most robust workflow management solution you can find today. Apache has worked on it well and added features that outnumber any other solution, even its predecessors. Here are some benefits that make it an ideal solution to manage data pipelines and workflows.
Constant Monitoring of Data Pipelines
If you want to manage your data pipelines well, you have to make sure they perform consistently. That requires constant monitoring of DAG execution and performance. Apache Airflow monitors the task status constantly. It shows the status on the front-end UI along with detailed logs on task execution and performance.
Additionally, if any DAG fails or is rescheduled, the tool sends you instant alerts by email. It also gives metrics on which tasks it monitored and which it retried. You also see how many times it retried, the last try, why the task failed, and more. With these metrics, you can easily find issues with your data pipelines and make sure you manage them well.
Lineage Tracking of Data Sources
Lineage is a relatively new feature in the latest version of Apache Airflow. With lineage, you can track all your data sources, where they come from, where they go and what happens to them. You can handle multiple data tasks easily, because the tool can show lineage between input and output data sources in graphs. Lineage helps you depict and analyze the relationship between those sources. It also makes them easier to manage.
Manage Data Pipelines with Triggers
Apache Airflow has Sensors that you can use to manage tasks and data pipelines based on triggers. You can set a precondition for the tasks to run. You can also set how often the tool must check for the set triggers. Moreover, you can choose the types of sensors you need, which simplifies the management of pipelines further.
Ability to Customize the Pipelines
Customization is the best tool in your hands when you want a solution made for your needs. Apache Airflow is already feature-rich. It also offers scalable customization, so you can create your own data pipelines, operators and sensors. You can shape them to match your requirements. That gives you an even more personal experience, and you can keep managing the data pipelines consistently.
Are You Ready to Leverage the Solution?
With all its capabilities, features and benefits, Apache Airflow is an ideal tool for your needs. However, you need to know how to use the tool at its best so that it doesn’t backfire on you. So, it’s important to work with professional expertise when you use Apache Airflow.
