Answer / Aditya Kumar
"Lazy evaluation offers several advantages in Apache Spark:nn1. Improved Resource Utilization: By delaying computations, Spark can better manage its resources, as it only performs necessary operations when needed.nn2. Enhanced Fault Tolerance: If a task fails during lazy evaluation, the entire job is not lost; instead, Spark re-executes the failed task on another worker, ensuring data integrity.nn3. Better Performance: Lazy evaluation allows for better scheduling and optimization of tasks by considering the dependencies between them, leading to improved performance."
