Data Agents: Agentic Data Systems

Traditional data systems face profound limitations in the AI era, relying on human-crafted pipelines, lacking semantic understanding of heterogeneous data, and operating through rigid, reactive processing. To address these challenges, we propose a new paradigm called the Data Agent, designed to manage, process, and ana...

DBCooker : A Database Kernel-Specialized Coding Agent Harness

Database kernels continuously incorporate new built-in functions to support diverse applications. Synthesizing these native functions is highly complex, as it requires identifying multiple internal units, placing them in the correct source files, and reusing specific internal references. Although recent advancement i...
