PAQO: A Preference-Aware Query Optimizer for PostgreSQL
Summary: PASQL extends SQL to constrain the plan space with user preferences and privacy/freshness constraints. PAQO, a preference-aware PostgreSQL optimizer, enforces PASQL constraints while optimizing queries, addressing visibility and data freshness in distributed settings.
