DoppelGanger++ in Action: A Database Replay System with Fast Dependency Graph Generation
Summary: DoppelGanger++: a database-replay system that generates much more compact dependency graphs far faster than prior work, removing a major pipeline bottleneck while preserving determinism and maximizing replay concurrency. Demo shows end-to-end capture/replay with a web tool that animates graph generation and visualizes internal data structures. (summarized by gpt-5-mini on Feb 09 2026)
