💡 Model Answer
In Apache Spark, a stage is a set of tasks that can be executed in parallel and share the same shuffle boundaries. When a job is submitted, Spark divides the work into stages based on transformations that require shuffling data (e.g., groupBy, join). Each stage contains tasks that process a partition of the data. Stages are executed sequentially, but tasks within a stage run concurrently across the cluster.
