BigData / Apache Airflow Interview Questions

What is the Grid view in Airflow 2.x?

The Grid view (introduced in Airflow 2.3 as a replacement for the Tree view) shows a matrix of DAG Runs on the X-axis and tasks on the Y-axis. Each cell represents a task instance colored by state (green=success, red=failed, yellow=running, etc.).

Key interactions:

Click a cell to inspect that task instance's logs, duration, and XCom output.
Filter by run type (scheduled, manual, backfill).
Group tasks by TaskGroup using the expand/collapse controls.

The Grid view is the primary view for diagnosing patterns of failures across multiple DAG Runs.
