Building a UI for Query Insights

Query Insights is a new feature in ClickHouse Cloud that provides users with an intuitive and accessible way to view and interpret their query log data. The system.query_log table contains valuable information about query performance, errors, and time-series metrics, but its complexity can make it difficult for less experienced users to interpret. Query Insights addresses this issue by making the data more interpretable and exposing important top-level query metrics. It also simplifies query debugging and optimization workflows, as well as providing context-based suggestions and insights from the query log. The feature is currently in its first iteration, with future improvements based on user feedback.
