Question 21. How does PySpark differ from MapReduce?

In this video, we explore the fundamental differences between PySpark and MapReduce, two powerful frameworks for distributed big data processing. While both are designed to handle massive datasets, they differ significantly in their execution model, speed, ease of use, and capabilities.

We’ll cover key aspects such as:

Programming Model: PySpark’s high-level APIs vs. MapReduce’s low-level Java-based API.
Execution Model: PySpark’s DAG-based in-memory computation vs. MapReduce’s disk-based processing.
Processing Capabilities: Real-time and streaming support in PySpark vs. batch-only processing in MapReduce.
Ease of Development: PySpark’s concise and user-friendly syntax compared to MapReduce’s verbose coding.
Use Cases: When to choose PySpark over MapReduce for your big data workflows.
By the end of this video, you’ll have a clear understanding of how PySpark and MapReduce differ and which one is better suited for specific big data scenarios.
