Robust Database Design: CliffGuard

Can physical database design remain effective when workload estimates are wrong?

CliffGuard is a principled framework for finding physical designs that are robust to workload uncertainty.

The problem

Design advisors can overfit imperfect workload estimates and recommend configurations whose performance degrades sharply when conditions change.

The approach

Model uncertainty explicitly and search for physical designs with robust performance across plausible workloads.
