Cost-Based Planning for Semantic Integration
How should CatDB select federation, local execution, caching, partial materialization, full materialization, or incremental refresh?
Question and scope
a calibrated cost model covering latency, transfer, cardinality, freshness, transformation, provenance, consistency, and source load.
Research artifacts
cost equations, statistics interface, adaptive choices, optimizer prototype, and ablations.
Evidence and evaluation
predicted versus observed costs and conventional optimizer baselines.
Claim boundary
global optimality under incomplete information.
