Ultraverse: An Efficient What-if Analysis Framework for Software Applications Interacting with Database Systems
Summary: Ultraverse unifies app- and DB-layer what-if analysis via dynamic symbolic execution, translating app code into compact SQL procedures and preserving semantics. Query dependency analysis prunes non-influential transactions and enables parallel replay of independent ones, delivering 7.7x–291x speedups on unmodified DBs and legacy apps.
