Good Code, Wrong Model. How to Benchmark AI Coding Agents for Distributed SQL

The blog post by Dmitry Sherstobitov discusses the challenges and solutions in benchmarking AI coding agents for distributed SQL systems, specifically focusing on YugabyteDB. The article highlights that while AI models are often well-trained on single-node PostgreSQL examples, they tend to produce inefficient or incorrect code for distributed systems due to a lack of understanding of distributed SQL requirements. To address this, a new benchmark was developed to evaluate code generation by AI models, emphasizing execution-based scoring and real cluster validation. The benchmark's structure includes prompts that reveal common anti-patterns, grounding levels to assess the model's knowledge, and a scoring engine that evaluates code against live clusters. The results show that grounding AI models with specific YugabyteDB skills significantly improves their ability to avoid anti-patterns and adopt distributed-native engineering practices. The blog concludes by providing resources for improving AI models' performance on distributed SQL tasks and invites readers to engage with further insights through Yugabyte's platforms.
