HoneyComb: A Parallel Worst-Case Optimal Join on Multicores

Summary: HoneyComb extends WCOJ to shared-memory systems by adapting HyperCube-style domain partitioning for all query variables, reducing skew. It builds CoCo, a sorted index, and a WCOJ rewrite that factors out redundant work for scalable parallel evaluation. (summarized by gpt-5-nano on Feb 09 2026)
