Synchronizing a database to Improve Freshness

Summary: Local-copy synchronization for autonomous data sources; defines freshness metrics and change models. Analytical evaluation of synchronization policies; 270-site, 4-month experiments show the proposed policy improves freshness vs current approaches. (summarized by gpt-5-nano on Feb 09 2026)
