DSABench: Benchmarking Source Discovery, Coordination, and Execution for Multi-Database Agents

We present DSABench to evaluate these capabilities jointly.

Key points

  • Most text-to-SQL benchmarks provide the target database.
  • In a large data catalog, however, choosing the sources is part of the problem: an agent must find every database needed for a request, determine how their results fit together, and execute the resulting workflow.
  • Executable contracts define source participation, cross-source dependencies, and source-local execution, while RouteEnv lets agents inspect public catalog evidence without revealing the gold annotations.
  • On ambiguous tasks, clarification improves exact branch-source recovery by 39.8-43.2 percentage points.
