Here are some basic airflow interview questions that you must be prepared to answer if you are a beginning data engineer or a newcomer to the data engineering field.
Explain how workflow is designed in Airflow?
An Airflow workflow is created using a directed acyclic graph (DAG). To put it another way, think about how a workflow can be broken up into independent tasks when creating one. To create a logical whole, the tasks can then be combined into a graph. Your workflow’s overall logic is based on the graph’s shape. You can decide which branches in an Airflow DAG to follow and which to skip during workflow execution. The last unfinished task could be restarted to allow workflows to continue after Airflow Pipeline DAG Airflow was completely stopped. When creating airflow operators, it’s crucial to keep in mind that they can be executed multiple times. Each task must be idempotent, or able to be carried out more than once without leading to unintended results.
