XDB in Action: Decentralized Cross-Database Query Processing for Black-Box DBMSes
Summary: XDB implements in-situ, decentralized cross-database query processing over black-box DBMSes, removing the mediator-wrapper engine and avoiding centralizing data. Prototype demonstrates optimizer and decentralized execution that push computation into sources, reducing data movement and provisioning overhead. (summarized by gpt-5-mini on Feb 09 2026)
