PTO: A Workload-driven Predictive Table Optimizer for Lakehouse Systems
Summary: Workload-driven table layout tuning for lakehouses: PTO predicts partitioning/sort/file-size/bin-packing params from query predicates, using heuristic candidate pruning + table sampling + Gradient Boosting to avoid exhaustive search. Implemented for Presto/Iceberg; significant latency gains on TPC-H/TPC-DS. (summarized by gpt-5-mini on Apr 11 2026)
