![]() Hooks and executors in the Airflow environment: Hooks are pieces of code that are invoked by operators to interact with databases, servers, and external services. DAGs can be created from configuration files or other metadata. Tasks are then grouped together to form DAGs. Operators can be grouped together to form upstream tasks. DAGs are composed of operators, which are nodes in the graph that represent an individual task. How Airflow Works – Build and Monitor WorkflowsĭAGs: Airflow enables you to manage your data pipelines by authoring and monitoring workflows as Directed Acyclic Graphs (DAGs) of tasks, which instantiates pipelines dynamically. The goal of the project was to enable greater productivity and better workflows for data engineers. Airflow is written in Python and uses the Django web framework. The open-source distribution is available through the Apache Software Foundation.Īirflow was originally created by Airbnb and was open sourced in June 2015. ![]() Learn, build, test and fail forward without risking unexpected cloud bills.Airflow is an open-source workflow management system designed to programmatically author, schedule, and monitor data pipelines and workflows.

ETL pipelines that extract data from multiple sources, and run Spark jobs or other data transformationsĮach of the services discussed has unique use cases and deployment considerations.Here’s an overview of some use cases of each service.Ĭhoose AWS Simple Workflow Service if you are building:Ĭhoose AWS Step Functions if you want to include: Let’s have a closer look at the benefits and drawbacks of each service. Using Airflow, you can author workflows as Directed Acyclic Graphs (DAGs) of tasks, and Apache Airflow can integrate with many AWS and non-AWS services such as: Amazon Glacier, Amazon CloudWatch Logs and Google Cloud Secret Manager. This powerful and widely-used open-source workflow management system (WMS) allows programmatic creation, scheduling, orchestration, and monitoring of data pipelines and workflows. Apache Airflow is an open-source workflow management platform for data engineering pipelines. What is Apache Airflow?įirstly, Apache Airflow is a third party tool – and is not an AWS Service. ![]() The states in your workflow can perform work, make choices, pass parameters, initiate parallel execution, manage timeouts, or terminate your workflow. State machines represent individual steps in a workflow diagram by containing a number of states. Your workflow can be visualized by state machines describing steps, their relationships, and their inputs and outputs. What are AWS Step Functions?ĪWS Step Functions enables you to coordinate distributed applications and microservices through visual workflows. Amazon SWF interacts with workers which are programs that retrieve, process, and return tasks.Īs part of the coordination of tasks, execution dependencies, scheduling, and concurrency are managed accordingly. The AWS Simple Workflow Service (SWF) allows you to coordinate work between distributed applications.Ī task is an invocation of a logical step in an Amazon SWF application. This article highlights the similarities and differences, benefits, drawbacks, and use cases of these services that see a growing demand. While these services have largely similar pricing, there are different use cases for each service.ĪWS Simple Workflow Service (SWF), AWS Step Functions and Apache Airflow all seem very similar, and at times it may seem difficult to distinguish each service. There are a number of different services and products on the market which support building logic and processes within your application flow. ![]()
