MariaDB High Memory Usage: What to Do?
In this mariadb tutorial we’ll walk you through the mariadb high memory usage problem. To fix this mariadb high memory usage problem, first check running SQL queries.
After you glance into the SQL queries running inside of your MariaDB database, check your MariaDB settings and keep in mind the values of the following settings, then adjust them as necessary:
Created_tmp_tables: Created temporary tables.
Innodb_buffer_pool_pages_data: The number of pages in the buffer pool with data.
Innodb_buffer_pool_bytes_data: The number of bytes in the buffer pool with data.
Innodb_buffer_pool_pages_dirty: The number of dirty pages in the buffer pool.
Innodb_buffer_pool_bytes_dirty: The number of dirty bytes in the buffer pool.
Innodb_buffer_pool_pages_flushed: The number of requests to flush pages from the InnoDB buffer pool.
Open_tables: The amount of open tables.
Open_tables: The amount of tables that haave been opened.
Threads_running: The amount of running threads.
Checking these MySQL settings makes you aware of how the memory is being used inside of your MySQL server database, and these settings will also provide useful information related to the InnoDB buffer pool and other things.
After you check these variables, optimize the variables related to InnoDB, and you should be good to go.
Also check some of the sql interview questions and answers below – if you’ve found yourself searching how to fix the mariadb high memory usage problem, you will certainly find these sql interview questions and answers for experienced developers and DBAs interesting:
Q: Is sql injection very dangerous? How to avoid it?
A: Yes, sql injection is a very dangerous security flaw. To avoid sql injection, avoid passing user input straight to a database.
Q: How does a sql index improve sql query performance?
A: A sql index improves database performance by acting as an “index” in a book: by using a sql index your database knows how to find your data in a quick fashion. If you’re after a sql indexes explained video we advise you watch one of our videos on a sql index and its performance.
Q: Explain sql in 100 seconds.
A: SQL is a programming language allowing for work with various RDBMS including mysql server, mariadb server, percona server, and others.
Q: Are sql interview questions for experienced developers and DBAs very difficult?
A: No, these sql interview questions for experienced DBAs aren’t very complex for a DBA worth their salt.
Q: Explain sql joins.
A: sql joins are used to combine rows from a couple of tables in a database management system.
Q: Is mariadb installation very difficult? Is there a difference between mariadb installation linux and mariadb setup on windows?
A: No, mariadb windows installation is pretty much the same as installation on Linux. We advise you to refer to the documentation and use the mysql_secure_installation script upon installation.
Q: Will you make a mariadb tutorial on sql indexes, sql queries, etc.?
A: Yes, if necessary, we’ll make a mariadb tutorial as well.
Q: MySQL password not working. What do I do?
A: Please run a search through our channel – we’ve made a SQL tutorial on this.
Q: What file should be used for mysql server configuration?
A: my.cnf or my.ini.
Q: What’s the mysql my.cnf location?
A: The location of the file can vary, but some of the most common locations include:
* /etc/my.cnf (the most common location.)
* /etc/mysql/my.cnf
* /[datadirectory]/my.cnf
* ~/.my.cnf.
Q: What are some of the most popular SQL commands?
A: CRUD queries are the most popular SQL queries. They can be used to create (insert), read (select), update, or delete data.
Q: What storage engine should we use in our MySQL install?
A: Use either InnoDB or Percona XtraDB. If there’s a necessity to run COUNT(*) queries, use MyISAM, because InnoDB and Percona XtraDB don’t store the row count internally while MyISAM does.
