How Dags Are Scheduled Along With Understanding How States Of Dags & Tasks Change

Explore the dynamics of DAG (Directed Acyclic Graph) states and task instances with Qubole in this insightful video:

Understanding DAG States:
- Learn about different states of DAGs, including running, success, and failed, and how they signify the progress of your tasks.
Task Instance States:
- Discover the 11 states of task instances, with emphasis on the top six states encountered in everyday usage, such as scheduled, running, and success.
State Transition Process:
- Gain insights into how states change as users interact with the web server, the scheduler picks up tasks, and the executor executes them, ensuring smooth workflow management.
Summary of Key Concepts:
- Review a summarized overview of DAG and task instance states to solidify your understanding of the concepts discussed.
Practical Demonstration:
- Witness the practical application of DAG and task instance states in the Airflow web server, observing state changes as tasks progress through the workflow.
