Stop Handcrafting Your Engine! GenDB-V: Towards AI-Generated and Formally Verified Database Systems

Read the original on arXiv Computation and Language →

GenDB‑V is a system that uses AI agents to automatically synthesize database engines tailored to specific hardware and workloads, while also providing formal verification of correctness. It introduces SQLSpec to formalize SQL semantics, enabling joint synthesis of efficient code and modular proofs that bridge low‑level execution to SQL semantics. Evaluations on TPC‑H and SEC‑EDGAR show significant speedups over existing engines and reveal correctness issues in alternative LLM‑based synthesis methods.

Breaking Database Lock-in: Agentic Regeneration of High Performance Storage Readers for Database Bypass

arXiv:2607. 07696v1 Announce Type: cross Abstract: Analytical workloads operating on data stored in external database systems face a fundamental bottleneck: data access is guarded entirely by the database driver, like JDBC or ODBC, forcing all reads through query execution and other driver layers that are not designed for bulk columnar analytics.

Breaking Database Lock-in: Agentic Regeneration of High Performance Storage Readers for Database Bypass

Analytical workloads operating on data stored in external database systems face a fundamental bottleneck: data access is guarded entirely by the database driver, like JDBC or ODBC, forcing all reads through query execution and other driver layers that are not designed for bulk columnar analytics. We present Jailbreak, an approach that bypasses the database engine entirely by reading storage files directly and materializing data as in-memory columnar buffers.
