You're working with a large dataset that needs to be partitioned and processed in chunks to improve efficiency. How can you achieve this using Airflow operators?

• A.Use the Split Operator to divide the data into smaller subsets and chain them with downstream processing tasks.
• B.Leverage the File transform operator to partition the data based on specific criteria within the operator itself.
• C.Implement a custom Python script to handle partitioning and then use the BashOperator to execute the script within the DAG.
• D.Configure the source system to provide the data pre-partitioned for efficient processing.

Which of the following is a best practice for organizing tasks within a DAG in Apache Airflow?

• A.Group tasks with similar functionalities using SubDAGs for better readability and maintainability.
• B.Place all tasks directly in the root DAG to simplify monitoring and execution.
• C.Use a single Pythonoperator to execute all tasks as functions for efficiency.
• D.Dynamically generate tasks at runtime to avoid defining them explicitly in the DAG.

What is the recommended way to handle dependencies between data quality checks in Apache Airflow to ensure that checks are performed in a specific sequence?

• A.Use the SequentialExecutor for the Airflow environment.
• B.Explicitly set task dependencies using the set_upstream or set_downstream methods.
