EVALUATION OF DATABASE QUERY PLAN ROBUSTNESS LANDMARKS USING OPERATOR MAPS OR QUERY MAPS

摘要

Computer-implemented systems and associated operating methods create and use an operator map to identify and evaluate database query plan robustness landmarks. The computer-implemented system comprises logic that creates a map evaluating performance of an implementation of a database engine operator during execution under actual operating conditions. The logic measures and maps performance for a selected range of runtime conditions including resource availability and data characteristics.
