Airflow is an open-source platform used to programmatically author, schedule, and monitor workflows.
Airflow allows users to define workflows as Directed Acyclic Graphs (DAGs)
It provides a web-based UI for visualization and monitoring of workflows
Airflow supports various integrations with different systems and tools
Tasks in Airflow can be Python functions, scripts, or external processes
A DAG in Airflow stands for Directed Acyclic Graph, representing a workflow of tasks with dependencies.
DAG is a collection of tasks with defined dependencies between them
Tasks are represented as nodes and dependencies as edges in the graph
Tasks can be scheduled to run at specific times or based on triggers
Example: DAG for ETL process - extract data, transform data, load data
