Use cases of Apache Airflow

Reading Time: 5 minutes Apache Airflow’s versatility allows you to set up any type of workflow. Apache Airflow can run ad hoc workloads not related to any interval or schedule. However, it is most suitable for pipelines that change slowly, are related to a specific time interval, or are pre-scheduled. Adobe Adobe is a software company famously known for multimedia and creativity products such as Acrobat Reader and Photoshop. Continue Reading

Triggers in Apache Airflow

Reading Time: 3 minutes The easiest concept to understand in Airflow is Trigger rules. Let’s understand the Trigger Rules in Apache Airflow. Why Trigger Rules? By default, Airflow will wait for all the parent/upstream tasks for successful completion before it runs that task. However, this is just the default behavior of the Airflow, and you can control it using the trigger_rule the argument to a Task.  Basically, a trigger_rule defines Continue Reading

Apache Airflow: Understanding Operators

Reading Time: 5 minutes An Operator is the building block of an Airflow DAG. It determines what will be executed when the DAG runs. They can be considered as templates or blueprints that contain the logic for a predefined task, that we can define declaratively inside an Airflow DAG. When an operator is instantiated along with its required parameters then it is known as a task. An Operator defines one Continue Reading

Dynamic DAGs in Apache Airflow

Reading Time: 4 minutes Airflow dynamic DAGs can save you a ton of time. As you know, Apache Airflow is written in Python, and DAGs are created via Python scripts. That makes it very flexible and powerful (even complex sometimes). By leveraging Python, you can create DAGs dynamically based on variables, connections, a typical pattern, etc. This very nice way of generating DAGs comes at the price of higher Continue Reading

Apache Airflow: Scaling Using Celery Executor

Reading Time: 4 minutes Apache Airflow is a platform to programmatically author, schedule, and monitor workflows. If you are new to Airflow, please go through my introductory blog. One of Airflow’s biggest strengths is its ability to scale. In this blog, we will find out how we can scale Airflow using executors. Overview In Airflow, even the local executor is extremely powerful as you can start scaling Airflow and Continue Reading

Apache Airflow: Writing your first pipeline

Reading Time: 3 minutes Before jumping into the code, you need to get used to what Airflow DAG is all about. it is important so stay with me, Airflow DAG? DAG stands for Directed Acyclic Graph. In simple terms, it is a graph with nodes, directed edges and no cycles. Basically, this is a DAG: We will learn step by step how to write your first DAG. Steps to Continue Reading

Creating DAG in Apache Airflow

Reading Time: 5 minutes In my previous blog, I have discussed about the Introduction to the Apache Airflow. In this blog, we will learn how to create a DAG for Airflow that would define a workflow of tasks and their dependencies.  What is DAG?
