XDB in Action: Decentralized Cross-Database Query Processing for Black-Box DBMSes
Summary: XDB enables federated queries across heterogeneous, black-box DBMSes without a mediating engine. In-situ optimization and decentralized execution exploit existing systems to reduce redundant data movement and provisioning overhead. (summarized by gpt-5.6-luna on Jul 24 2026)
