Graph Transformers for Query Plan Representation: Potentials and Challenges
Summary: Finds Graph Transformer Networks (GTNs) excel at query-plan representation (new taxonomy) but degrade with scarce training data. Proposes data augmentation and replacing LM-style components in GTNs, yielding SOTA on JOB/TPC-H/TPC-DS and TPC-DS→TPC-H transfer. (summarized by gpt-5-mini on Feb 09 2026)
