Apache Airflow Best Practices

Getting Started with Airflow 2.0

In modern software development and data processing, orchestration plays a pivotal role in ensuring the coordination and execution of complex workflows. As organizations strive to manage their ever-growing data and application landscapes, the need for an efficient orchestration system becomes paramount.

With Airflow 2.0 having been released for some time and moving quickly to increase its capabilities, we elected to distill our experiences in operating Airflow to help others by showing them patterns that have worked well for others in the past.

Our goal with this book is to help engineers and organizations adopting Apache Airflow as their orchestration solution get the most out of their technology selection by guiding them to better choices as they go through their adoption journey and scale.

In this chapter, we will learn what data orchestration is and how it is applied to several industries facing data challenges. In addition, we will explore...

What is data orchestration?

In today’s data-driven world, organizations face the challenge of handling vast amounts of data from diverse sources. Data orchestration is the key to managing this complex data landscape efficiently. It involves the coordination, automation, and monitoring of data workflows, ensuring the smooth execution of tasks and the timely delivery of valuable insights.

Orchestration, in the context of software development and data engineering, refers to the process of automating and managing the execution of interconnected tasks or processes to achieve a specific goal. These tasks might involve data processing, workflow scheduling, service provisioning, and more. The purpose of orchestration is to streamline the flow of operations, optimize resource utilization, and ensure that tasks are executed in a well-coordinated manner.

Traditional, manual orchestration is cumbersome and prone to errors, especially as the complexity of workflows increases. However...

Exploring Apache Airflow

Apache Airflow is known within the data engineering community as the go-to open source platform for “developing, scheduling, and monitoring batch-oriented workflows.” (Apache.org Airflow documentation: https://airflow.apache.org/docs/apache-airflow/stable/index.html)

Apache Airflow has emerged as the go-to open source platform for data orchestration and remains the leader as a result of its active development community. It offers a robust and flexible solution to the challenges of managing complex data workflows. Airflow enables data engineers, data scientists, artificial intelligence (AI)/ML engineering, and MLOps and DevOps professionals to design, schedule, and monitor data pipelines with ease.

The power of Apache Airflow lies in its ability to represent data workflows as directed acyclic graphs (DAGs). This intuitive approach allows users to visualize and understand relationships between tasks, making it easier to create and maintain...

Core concepts of Airflow

Apache Airflow is a dynamic, extensible, and flexible framework that allows for the building of workflows as code. Airflow allows for the definition of these automated workflows as code. This allows for better code versioning, development through CI/CD, easy testing, and extensible components and operators from a thriving community of committers.

Airflow is known for its approach to scheduling tasks and workflows. It can take advantage of CRON scheduling or its built-in scheduling functions. In addition, features such as backfilling, allowing for the rerun of pipelines, allow for going back and updating pipelines if the logic changes. This means it has powerful operational components that need to be accounted for as part of the design.

Following these guidelines will help you lay a foundation for scaling your Airflow deployments and increase the effectiveness of your workflows from both authorship and operational viewpoints.

Why Airflow may not be...

Skills to use Apache Airflow effectively

It isn’t sufficient to just know Airflow; there are other skills that are required and will impact your team’s effectiveness at providing value with Airflow. As you’re reading this book, think about your teams’ skills in the following areas to understand if you need additional support or capabilities to make the most out of your platform:

  • Python: DAGs and plugins are written in Python. As such, in order for Airflow to be effectively adopted, you should be able to write and understand Python code.
  • Application testing: Your company should have relatively mature testing processes and practices in place to ensure that the plugins you write and the DAGs you author can be reasonably expected to function as intended. The team responsible for the health of your Airflow instance(s) and plugins should be able to help teams prepare for upgrades, and the teams responsible for writing workflows should be able to run...

Summary

In this chapter, we spent time learning the basics of what data orchestration is and what problems companies and engineers are facing today. In addition, we introduced Apache Airflow, the leading data orchestration and workflow management tool. We also covered what you can expect over the course of this book. It is important to remember that Apache Airflow requires multiple baseline tools and knowledge areas to be most successful. Although these areas are needed for best use, each is a learnable topic and can be picked up at a quick pace.

At the core of Airflow use is Python code. To be the best data engineer using Airflow, you need to understand the core concepts of Python code and how it will orchestrate your stack of data tools. Taking time to review these core concepts and understand the use cases that are being tackled by Airflow will lead to scalable systems of code and optimization opportunities.

In the next chapter, we will introduce the basics of DAGs and tasks...

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
