Now, refresh the Airflow dashboard it will show the DAG in the list. To install the Airflow, we will use the following pip command.This direction makes it a directed graph. The node represents the task, and the directed edges represent the dependencies between tasks.įor example, if task X connected with the edge and pointed to task Y, task A must be finished before task B can begin. The structure of the DAG (tasks and their dependencies) is specified as code in Python scripts.ĭAG of data pipeline is the best way to make task relationships more apparent. These tasks are organized in such a way that the relationship and dependencies are maintained. It provides an excellent user interface and monitors and fixes issues.Īirflow uses the DAG (Directed Acyclic Graph), a collection of all tasks users want to run. It assures that each task in the data pipeline will get executed in the order and each task gets the required resources. It is a workflow engine that easily schedules and runs the complex data pipeline. What is Apache Airflow?Īpache Airflow is a tool that is popularly used in the data engineering fields. Moreover, these tasks are required to perform in a specific order. Push the transformed data to the weather dashboard.Īs we can see that these are the set of tasks in the pipeline.Make some transformations on the fetched data (e.g., converting temperatures from Fahrenheit to Celsius or vice versa) so that the data suits our purpose.Fetch weather forecast data from a weather API.We need to perform the following tasks to implement this live weather dashboard. For example - We want to create a weather API that forecasts the weather in the upcoming week. What are Data Pipelines?ĭata pipelines contain multiple tasks or actions that must be executed to get the desired result. Before dive deep into this topic let's understand the basic concept of the Airflow and why it is popular. We will discuss all the operators of airflow however our primary aim is explore the Python operators and how we can use it. In this tutorial, we will learn about the Apache Airflow and its operators.
