Unveiling the Mystery How the DESC Command Creates Temporary Tables in MySQL MariaDB IntroductionFor the past eight months our team has been on a detective mission A mysterious graph started showing usage when some code went live and it s been a rollercoaster ride trying to figure out the root cause The culprit The MySQL or MariaDB DESC DESCRIBE or EXPLAIN table commands The graph in Zabbix for temporary tables created per second began to fluctuate and we were at a loss as to why The situation escalated during a recent spike in usage when our server became overloaded and we started to notice a lot of DESC table commands in our process list This article uncovers the behavior of the DESC command and its link to temporary table creation a discovery that illuminated our understanding and allowed us to resolve the issue What is the DESC Command The DESC command in MySQL or MariaDB is used to describe the structure of a table It provides information about the columns types and other properties of the table Here s a simple example DESC employees This would display the structure of the employees table including column names data types etc Field Type Null Key Default Extra id int NO PRI NULL first name varchar YES NULL last name varchar YES NULL salary decimal YES NULL hire date date YES NULL The Unexpected Behavior Temporary Table CreationWhat caught our attention was that in MariaDB the description Creating Temporary Table appeared when running the DESC command This was puzzling and led us to investigate further Why are Temporary Tables Created Temporary tables are often used to store intermediate results for complex queries However we didn t expect them to be linked to the DESC command After digging into the MySQL MariaDB documentation and source code we realized that the DESC command indeed creates a temporary table to store and display the structure of the queried table The Impact on PerformanceThe frequent creation of temporary tables was taking a toll on our system The server became overloaded and the website s performance deteriorated Our code was using the DESC command to populate database mappers and it seemed that the cache was not working properly This resulted in an excessive number of DESC commands leading to the unexpected creation of temporary tables How We Fixed the IssueOur solution involved correcting the caching mechanism Once the cache was functioning properly the number of DESC commands plummeted and the graph flatlined Here s a brief outline of the steps we took Analyzed the Caching Behavior We found that the cache was not retaining the DESC command results Implemented Proper Caching We modified our code to properly store and retrieve the table descriptions Monitored Performance We closely watched the system performance and the graph in Zabbix The result was a noticeable improvement ConclusionThe discovery that the DESC command creates temporary tables in MySQL MariaDB was an unexpected revelation that solved a long standing mystery By understanding this behavior and implementing proper caching we were able to boost our system s performance Sometimes the solutions to complex problems are hidden in the most unexpected places This experience reminds us to leave no stone unturned in our pursuit of understanding and optimizing our systems Whether you re a seasoned database administrator or new to MySQL MariaDB I hope this article sheds light on a lesser known aspect of these database systems and helps you in your journey |
