The collection of the various tasks you plan to complete, arranged to display their dependencies and relationships, is called a Directed Acyclic Graph, or DAG.
Tasks
These are the individual activities or units of work performed in DAG. Examples include running an SQL query, reading from a database, and so on.
Operators
Within a DAG, operators serve as building blocks for the creation of particular tasks. Each operator specifies the kind of work that needs to be done.
Scheduling
A scheduler is used to accomplish scheduling in Airflow. It keeps an eye on all open tasks and DAGs, and when the dependencies are satisfied, it starts the task instances.
XComs
"Cross-communication" is shortened to "XComs." It makes it possible for tasks to communicate
Hooks
An abstraction layer or interface to external platforms or resource locations is what a hook is.
Web UI
The Web UI gives a pleasing interface for visually monitoring and troubleshooting data pipelines.
