Understanding Jobs, Stages, Tasks and Partitions in Apache Spark under 60 seconds #interview
Jobs: Refers to a sequence of tasks triggered by an action, like writing data to storage or displaying results.
Stages: Break down jobs into smaller units to optimize parallel execution.
Tasks: Basic units of work within a stage, each operating on a partition of data. Spark schedules tasks dynamically based on available resources.
Partitions: Divides data into smaller chunks, allowing parallel processing across multiple nodes in a cluster. It's crucial for scalability and performance.
Most commonly asked interview questions when you are applying for any data based roles such as data analyst, data engineer, data scientist or data manager.
