In database management, performance optimization is a crucial aspect of maintaining efficiency, scalability, and responsiveness. Traditionally, database administrators (DBAs) had to manually tune queries, optimize indexes, and adjust execution plans to improve SQL Server performance. With the introduction of Intelligent Query Processing (IQP) in SQL Server 2019 , Microsoft has significantly enhanced the query execution process by integrating adaptive and automatic performance tuning mechanisms . IQP is a set of automated performance enhancements that reduce the need for manual query optimization, ensuring that workloads run more efficiently with minimal changes to application code. This feature helps in solving common query performance issues like poor cardinality estimates, parameter sniffing, and excessive memory grants. What is Intelligent Query Processing (IQP)? Intelligent Query Processing (IQP) is a collection of automatic query performance enhancements designed to optimi...
