QueryFormer: A Tree Transformer Model for Query Plan Representation
Summary: QueryFormer, a tree-structured Transformer, encodes query plans, addressing long information paths and parent-child dependencies. It integrates histogram statistics into plan encoding and yields improvements across four ML-based optimization tasks. (summarized by gpt-5-nano on Feb 09 2026)
