Outline

This paper explores recent trends in integrating large-scale language models (LLMs) into SQL queries to enhance data analysis. Despite the advantages of LLM-based SQL queries offered by companies like Amazon, Databricks, Google, and Snowflake, open-source solutions often lack functionality and performance. This study uses two open-source systems and one enterprise platform to analyze five representative queries and exposes the functional, performance, and scalability limitations of current SQL-based LLM integrations. We identify three key challenges—enforcing structured output, optimizing resource utilization, and improving query plans—and propose initial solutions to address them, demonstrating performance improvements. We suggest that tight integration between LLMs and DBMSs is crucial for improving the scalability and efficiency of LLM-based SQL queries.

Takeaways, Limitations

Takeaways:
Integrating LLM and DBMS to improve the performance and functionality of SQL query-based data analysis.
Suggesting ways to improve an open-source LLM-based SQL query system (enforcing structured output, optimizing resource utilization, and improving query plans)
Emphasize the importance of tight integration to improve the scalability and efficiency of LLM-based SQL queries.
Limitations:
Initial research using limited open-source systems and query counts.
Further research is needed to determine the generality and applicability of the proposed solution to real-world environments.
Lack of extensive experimentation and analysis on various types of LLMs and DBMSs.
