Top 10 Tips and Tricks That Any Serious MySQL Database Developer Should Know

Just like MariaDB, My SQL is also the most popularly used database management system. However, it is complicated to use and with more and more updates its keep on getting tougher to crack. So, here are some tricks which can help both experts and beginners Click Here in their My SQL journey:

  • Use workload profiling tools

To examine a server’s response time you can use workload profiling tools. These tools put together similar queries and help you to identify the ones which are running slowly as well those which are fast.  All the queries are represented in a task table in decreasing order based on their response time. Identification of the most time-consuming queries will allow you to focus efforts in the right areas.

  • Partition MySQL tables

In the beginning, My SQL tables will be small but in some time they will rapidly grow to hundreds of thousands of rows thereby increasing the query response time. Then the only solution is to partition the My SQL tables. Partitions can have as many rows and columns and help to reduce query response time. However, this feature is not available in all My SQL versions so it would be best to run SHOW PLUGINS to confirm whether your My SQL has it or not.

  • Enumerations and My SQL:

Enumerations also called ENUMS are a complicated tool in MYSQL and the programmer must apply it very carefully in the database. They should keep in mind the rules and behavior of the ENUM functionality to prevent rework. Failure to do so will result in re-entering all the names, fields and values once again.

  • Use an appropriate storage engine:

My SQL has only two storage engines called InnoDB and MyISAM. MyISAM is a great choice for beginners as it has simple functions. InnoDB, on the other hand, is more complex and allows less freedom for developers to navigate through the data. Out of two MyISAM is better for securing data.

  • Auto-increment feature:

This is one of the best features of best features of MySQL. Under the Autoincrement Column Index while inserting a new row the function will automatically calculate and apply the values in the table.  It’s not always available in default settings so the settings can be changed to make it a default function.

  • Make sure you have the four essentials:

The My SQL server requires four essentials i.e. CPU, memory, disk and an active network.  If any four of these is weak, or overloaded, then the performance of the database server will be greatly impacted.

Choosing good quality hardware (i.e. CPU, memory, and disk) will ensure the database works efficiently. But all the four components should complement each other. For example, an organization may have a fast CPU and ample amount of disk space but not enough memory. This will affect the performance of the database. The only solution will be to increase memory which will be able to store all the server data.

Also, troubleshooting should be done to check the performance of all four components, this will help to identify whether they are performing poorly or are completing too much work. Do this will help to identify and solve problem areas.

  1. Don’t form a queue:

A queue is something which can be formed during development without any intention. One good example, Is that a developer may set a condition that a worker cannot claim an item before completing a task than a queue will automatically get created.

Formation of a queue in a database will lead to 2 major problems: The workload will be handled in a queue and a developer will not be able to perform two tasks at the same time. The pending and completed tasks will be presented in the form of a table which will occupy memory space. In addition, this will reduce the loading time in MySQL.

  • Query Caching:

This is one of the most effective methods to boost the performance of MySQL servers. It is automatically enabled in MySQL and it helps to retrieve results of queries which have been run multiple times.  But you won’t find this function in the current date (CURDATE) query. So to enable it you will have to type a PHP text before the query.

  • Add EXPLAIN keyword to select queries:

This is the simplest tip which both beginners and experienced developers can easily utilize. They only need to add the EXPLAIN keyword in front of a complex SELECT query after which the result will present in a simple table format. This function helps to gauge the performance of the query and which indexes have been utilized.

  • Enable delay_key_write function:

By default, this function is turned off in the MySQL database because if it experiences any crashes than the entire database will get corrupted. So why should you enable it you may ask? This is because if you enable the delay_key_write function the database will not erase the MyISAM key file after you type it. So when you do another write up in the future you will get the previously saved coding and also save a lot of time. However, this function is not compatible in all MySQL versions and you will have to check compatibility in the original MySQL site manual.

Final Words:

During web development, it has been found that developers use MySQL database with many kinds of programming languages to create striking website designs. The most common one which is used is PHP.

But, in PHP development the version hype has led people to question are the latest versions of PHP compatible with MySQL? Well, all the latest PHP 7 versions support MySQL updates. So the above tricks will definitely help developers to code smoothly.
