SQL Query Optimization and Query Rewriting

Research on SQL query rewriting, equivalence, program synthesis, database performance, physical design, and AI for query optimization.

How can a system find a faster query without changing what the query means?

GenRewrite and SlabCity study semantics-preserving query transformation; CliffGuard studies robust physical design under workload uncertainty.

Selected research

  • GenRewrite: LLM-assisted query rewriting
  • SlabCity: whole-query optimization using program synthesis
  • CliffGuard: robust physical database design
