Distributed Computing Is Not a Panacea for Big Data: Prioritize Single‑Node Performance First

While distributed clusters are popular for big‑data processing, they are not a universal solution; tasks that are hard to partition or involve heavy cross‑node communication often perform better on a well‑optimized single machine, making a careful analysis of workload characteristics essential before scaling out.
