It is not just another SQL tuning tool
There are not many SQL tuning tools for SQL Server database, but most of them are focused on plan visualization or query plan analysis, it is not helpful if you don’t have in-depth SQL tuning knowledge and are not willing to spend extra effort to tune a SQL apart from your daily duties. If you are eager for getting a one-button-solution tool that can tune a SQL statement automatically without the need for your intervention, then Tosska SQL Tuning Expert for SQL Server may be your only choice.
Expensive SQL tuning effort by the human expert
It may be up to days or weeks for a DBA or experienced SQL developer to tune a problematic SQL statement. SQL tuning is a very skillful job that not many developers can carry out in an enterprise. Should such expensive and valuable time be saved and used for other even more productive tasks inside a company?
What is machine tuning for SQL statements?
Tosska SQL Tuning Expert is a SQL tuning tool that optimizes your SQL statements without the need for user involvement.
The machine tuning for SQL statements is a proprietary technology invented by Tosska to mimic a human expert SQL tuning process, in which the engine tries every possible effective SQL rewrite and SQL Server Hints combinations for a SQL statement to improve the execution speed within the given quota. As the permutation of SQL rewrites and Hints combinations to a SQL statement is so huge, it is impossible for a human expert to accomplish it for complex SQL statements within a short time. Furthermore, there is also no way for a DBA or developer to guarantee that the best solution is found after a lot of manual trials and errors.
World’s Leading A.I. SQL Rewrite technology for SQL Server database
Manually rewriting SQL syntax to tune a SQL statement is commonly adopted by experienced developers and DBAs, but the effort and cost to rewrite a SQL statement is quite expensive. It requires an in-depth SQL tuning knowledge developer to spend hours or even days to rewrite and test a problematic SQL statement, and the tuning result might not be the best among most potential SQL rewrites due to the limitation of manual effort.
Tosska A.I. SQL Rewrite Engine is the world’s leading machine SQL Rewrite technology for SQL Server database. It not only saves the developer’s time to rewrite a problematic SQL statement to make it faster, but it also explores the potential best SQL syntax that even an experienced developer cannot discover. Moreover, Tosska A.I. rewritten SQL syntax can work with our Hints-injection algorithm to further explore more potential query plans that even most experienced developers cannot achieve.
Probably the World’s First A.I. SQL Tuning Tool for SET ROWCOUNT N
Set Rowcount N causes SQL Server to stop processing the query after the specified N rows are returned. There are not many people who know that the SQL’s query plan may be affected by this setting, some SQLs’ performance may be degraded due to the SQL Server tries to optimize the SQL for the first N rows, but resulted in an even worse query plan. It is difficult for developers to tune this kind of problem without a good tool. Tosska SQL Tuning Expert for SQL Server is the first tool that can solve this problem automatically with our A.I. engine.
Powerful Cold Cache SQL Tuning for Infrequent Executed SQL Statements
For SQL statements that are not executed frequently, so that the relevant data is no longer exists in the buffer cache, a cold cache will significantly affect the performance of a SQL statement. A good performance SQL for hot cache may not be performing well in a cold cache environment. Experience developers will tune their SQL running well for both scenarios. Tosska SQL Tuning Expert for SQL Server provides a handy function for users to benchmark SQL alternatives in both environments without complicated manual operations.
Best solution without trial and error
With Tosska SQL Tuning Expert for SQL Server, you no longer need to rewrite or try every possible Hints combination manually for a problematic SQL statement to explore potential better performance execution plans, since all those hard tasks are released by our embedded AI engine. Our intelligent engine will help you to find every possible rewrite and Hints combination to improve your SQL speed without the need for your intervention. You just sit back, relax, and wait for the best SQL alternative to come up on your screen.
Provide even better than a human expert’s solution
Tuning SQL is a time-consuming job that requires in-depth knowledge of SQL tuning skills and most SQL developers are not trained to accomplish this job apart from their daily development tasks. Furthermore, there is no way for a DBA to explore all alternative execution plans within a short time. The following screenshot shows that Tosska SQL Tuning Expert can explore thousands of SQL alternatives in just a few minutes that may require a human expert months’ effort to do so.
After benchmarking partial or all SQL alternative execution plans, the best SQL alternative will be displayed with the Original SQL statement side by side on the screen. The process is fully automatic without the need for user’s involvement and the result is the best out of thousands of potential execution plans that SQL Server can generate for the SQL statement. This exhaustive search and test process is impossible to be accomplished even by a human expert.
Uncompromised SQL tuning solution within a manageable time
It is known that the longer you spend on the SQL tuning process, the more chance you may get a better SQL alternative. It is also true in Tosska SQL Tuning Expert that the user can adjust the Intelligent Level to control the time spent on a specific SQL statement according to the complexity of your SQL statement. For complex SQL statements with huge potential execution plans, users can allocate more resources and time to explore the ultimate performance solution for SQL statements.
