To configure intelligent query processing (IQP) in Microsoft Azure SQL Solutions, you can leverage various features and settings that enhance the performance and compatibility of your database queries. IQP introduces advanced query processing capabilities, allowing you to optimize query performance, improve reliability, and simplify query tuning.
– Navigate to your Azure SQL database in the Azure portal.
– Under the “Intelligent Performance” section, select “Automatic Tuning.”
– Enable the “Automatic tuning” option to allow the system to apply performance recommendations automatically.
– In the Azure portal, go to your Azure SQL database.
– Navigate to the “SQL databases” section and select your database.
– Go to the “Overview” section and click on “Configure”.
– Under “Settings,” choose “Compatibility level.”
– Select the appropriate compatibility level for your database (e.g., SQL Server 2019).
– Adaptive Join: Helps optimize join queries by dynamically selecting the join algorithm based on actual data.
SELECT *
FROM Table1
INNER JOIN Table2
ON Table1.Column = Table2.Column
OPTION (USE HINT('ENABLE_ADP'));
– Batch Mode Memory Grant Feedback: Adjusts memory allocation for query execution based on actual data.
SELECT *
FROM Table
WHERE Column = 'Value'
OPTION (USE HINT('ENABLE_QUICK_MODE'));
– Interleaved Execution: Enables efficient execution plans for queries with interleaved execution points.
SELECT *
FROM Table
WHERE Column1 = 'Value1' OR Column2 = 'Value2'
OPTION (USE HINT('ENABLE_INTERLEAVED_EXECUTION'));
– Query Store captures query performance information and stores it for analysis.
– In the Azure portal, navigate to your Azure SQL database.
– Under the “Intelligent Performance” section, select “Query Store.”
– Enable the “Query Store” option to start collecting query performance data.
– Keeping statistics up-to-date ensures the query optimizer can generate efficient execution plans.
– Run the following command to update statistics:
UPDATE STATISTICS TableName;
– Intelligent Insights provides intelligent recommendations to improve query performance.
– In the Azure portal, go to your Azure SQL database.
– Under the “Intelligent Performance” section, select “Intelligent Insights.”
– Review the recommendations provided and apply appropriate changes.
By configuring intelligent query processing (IQP) using the features and settings mentioned above, you can optimize query performance, improve reliability, and simplify query tuning in your Azure SQL Solutions. Remember to monitor and analyze the performance of your queries regularly to ensure ongoing optimization.
