Processing Theta-Joins using MapReduce*
Summary: Maps arbitrary theta-joins to MapReduce via a simple key-equality data-flow model; supports non-equi joins without changing MR. Introduces 1-Bucket-Theta, a randomized, memory-aware algorithm needing only input cardinality, near-optimal for many joins. (summarized by gpt-5-nano on Feb 09 2026)
