What are the main differences in performance between Hadoop and Spark?
Hadoop is disk-based and processes data in batches, while Spark is in-memory and processes data in real-time, making Spark generally faster.
Can you explain why Spark is faster than Hadoop?
Spark's in-memory processing reduces the time spent on disk I/O, allowing it to handle data much quicker than Hadoop's batch processing.
Are there specific use cases where Hadoop performs better than Spark?
Yes, Hadoop is better for large-scale batch processing and when working with massive datasets that don't fit in memory.
Which one should I choose for my big data project?
It depends on your project's requirements. If you need real-time processing, go with Spark; for batch processing, Hadoop is suitable.
