MySQL profiling for a better Database driven Application’s Performance

Posted by MySQL NEWS No Comment yet

With the increasing revolution in Information Technology, the need for robust and high performing databases is increasing by the passing day. The dependence of online operations by the enterprises is the driving force behind the requirement of a high performing and secured database that could efficiently manage data at huge scale.

That is why enterprises are witnessed trying their best to ensure that their databases are streamlined and work with higher efficiency by performing database optimization on a regular basis. The regular SQL performance tuning of the databases ensure that all the possible reasons that could cause a slowdown are proactively eliminated to ensure seamless data access and uninterrupted operations.

These activities are conducted under the expert supervision of experienced SQL DBA consultants who tend to ensure that the database delivers high performance by conducting regular tuning activities such as MySQL profiling for enhanced database based application’s performance.

In this article, let us understand what MySQL profiling is and how it is performed to ensure a better performance of an enterprise application that is based on MySQL database.

What is MySQL profiling?

MySQL profiling is a way to analyze the overall performance of an application that is driven by the MySQL database. Such an application which is largely dependent on the MySQL database comprises of many MySQL which are important for the functional operations of the application. It is, therefore, important to know whether these MySQL query statements that form a part of the application’s code are running efficiently or not.

In order to analyze the performance of these MySQL queries within the application’s code, diligent DBAs play an important role by conducting MySQL profiling to ensure that all the possible bottlenecks are eliminated and the application delivers high performance with better response time.

MySQL profiling consists of various techniques such as MySQL server performance profiling and the use of SQL query profiler.

How to perform Server Profiling with MySQL slow query profiler

MySQL slow query profiler gives a detailed insight into the SQL queries and helps in identifying the slow queries that the DBA could further optimize to ensure a better response time of the app. Details such as response time of the query, CPU usage, use of other resources such as I/O, network and Memory are the key parameters which could make a query need optimization. By optimizing queries, you can ensure that the CPU is able to process a higher number of SQL queries within the stipulated time which can significantly increase the app’s performance especially when the data volume is huge.

Based on the above insights, you can further investigate about the queries that are not performing well by using tools in MySQL such as EXPLAIN, STATUS, and SHOW which would help you further know the cause and identify the exact queries that are potentially slow.

You can set up server variables such as long_query_time for the SQL query profiler which could help in identifying the slow queries in the log. This way you would know which query is taking more than stipulated time to run and can identify the cause.

MySQL Query Optimization is a process that requires a diligent and proactive approach to find the best suitable way to implement a query saving time and resources of the MySQL Database Server.

During MySQL Query Optimization often the DBA writes the complex subqueries using temporary tables so as to improve their turnaround time and make them execute faster than before. Joins and Indexes are also used for optimizing queries. These tend to identify the queries with over workload and decrease it by bringing out alternative ways to execute the query.

It is always up to the DBA professionals who use their knowledge, experience, and expertise to optimize the slow queries in the best possible manner for faster and seamless performance of the database.

Way ahead for better Database performance

Although Server Performance Profiling gives you an insight into the areas causing slowdowns, it is always important to find the best solution for optimum performance of the Enterprise Database.  A diligent DBA professional makes sure to find the details and come out with the most feasible solution every time a slow query surfaces the log without compromising the functionality.

Striking the right way comes with experience, and when you are hiring a DBA it is a very important factor to look for. If you are looking to drive your business’s app in a much efficient manner, then MySQL profiling is something you must consider.
