Hydro: A Heterogeneous Distributed Database System

Summary: Global serializability in heterogeneous DBMS via ROLL objects and Serialization Graph Test; deadlock-free. Atomic commitment via 2PC; HYDRO-I protects writes to PREPARED; HYDRO-II increases concurrency but lacks PREPARED, raising commit overhead. (summarized by gpt-5-nano on Feb 09 2026)
