Apache Hadoop started as batch: simple, powerful, efficient, scalable, and a shared platform. However, Hadoop is more than that. It's true strengths are:
- Scalability – affordable due to the open-source nature of Hadoop and its use of commodity hardware.
- Schema on read – save everything in raw form.
- Data is better than algorithms – more data and a simple algorithm can be much more meaningful than less data and a complex algorithm.
