Map-Reduce-Merge: Simplified Relational Data Processing on Large Clusters

Summary: Extends Map-Reduce with a Merge phase to efficiently process related heterogeneous relational data on large clusters. Merge consolidates data already partitioned and sorted (or hashed) by map and reduce, enabling relational algebra operators and multiple join algorithms. (summarized by gpt-5-nano on Feb 09 2026)
