Abstract
Computer-implemented systems and associated operating methods use performance maps created by evaluating robustness of a database operator, query plan, or query to analyze health of a currently-executing query. The computer-implemented system comprises logic that receives one or more robustness maps of measured database system performance acquired during database execution in a predetermined range of runtime conditions. The logic analyzes state of a currently-executing query by locating the query's performance on the robustness maps.
