Airflow uses directed acyclic graphs (DAGs) to represent a workflow. Workflows in Apache Airflow are a collection of tasks having dependencies on each other. How do we define workflows in Apache Airflow? Stock Price Prediction Project using LSTM and RNN View ProjectĪirflow isn't an ETL tool, but it can manage, structure, and organize data transformation pipelines, Extract, Transform, and Load(ETL) pipelines, and workflows, making it a workflow orchestration tool. And this can work simultaneously to perform multiple tasks and dependencies. Once we integrate airflow into our workflow (let's say an ETL task that you want to run daily at 1 pm), we can also visualize our data pipelines' dependencies, progress, logs, code, trigger tasks, and success status. It helps to manage any ETL (Extract, Transform, Load) operation and data pipelines. What is Apache airflow?Īirflow is an open-source workflow management tool by Apache Software Foundation (ASF), a community that has created a wide variety of software products, including Apache Hadoop, Apache Lucene, Apache OpenOffice, Apache CloudStack, Apache Kafka, and many more.Īpache airflow helps to conduct, schedule, and monitor workflows.
