GenDB-V database benchmark speedup questioned as overfitting
What happened
On November 11, Hacker News featured Thomas Neumann's analysis of GenDB-V's database benchmark results. The report says GenDB-V's speedup over Umbra and DuckDB ranges from 22x to 61x, and Neumann questions that performance. He argues the gains depend on over-specialization for TPC-H, making it a case of database benchmark overfitting. The report contains only this analysis and challenge, with no response from GenDB-V or follow-up verification.
