Answer / Subhay Chandra

Apache Spark offers several advantages over MapReduce in terms of speed, ease-of-use, and flexibility. Some key benefits include:
1. In-memory computing: Spark can cache frequently accessed data in memory for fast reuse, which makes it much faster than MapReduce.
2. Directed Acyclic Graph (DAG) execution: Spark creates an acyclic graph of tasks and executes them efficiently with minimal dependencies between the tasks. This leads to better performance compared to MapReduce's batch processing model.
3. Rich APIs for data processing: Spark provides high-level APIs for Java, Scala, Python, and R that make it easy for developers to write scalable applications quickly.
4. Streaming and interactive queries: Spark has built-in support for real-time streaming, which is not supported by MapReduce natively.
