Introducing the Query Tuning Agent: Optimize Your Most Complex Workloads

This post introduces the AI-powered Query Tuning Agent, a new capability that automates the diagnosis and recommendation of query optimizations for SingleStore's distributed execution engine. It details the agent's pipeline, including profile ingestion, normalization, bottleneck detection, knowledge base search, and recommendation generation. Specific technical contributions include the agent's ability to analyze distributed join types, data skew, shard key effectiveness, sort key performance, and cardinality estimations, providing SingleStore-specific advice. It also outlines the safety mechanisms, such as read-only operations, transactional rollbacks, and semantic validation, and describes its integration points within the SingleStore portal and future plans for an MCP skill.
