Apache Hadoop vs Apache Spark vs Apache Wayang: The Evolution of Big Data Processing

Apache Wayang became an Apache Top-Level Project in December 2025, reflecting a shift in how modern data architectures are designed. This article explains how big data processing evolved from Hadoop’s batch-oriented MapReduce model to Spark’s in-memory execution, and why cross-platform optimization is now necessary as analytics spans databases, streaming systems, and distributed engines. Drawing on peer-reviewed research and benchmark results, it outlines how Apache Wayang addresses the growing fragmentation of enterprise data platforms.
