Variables are quite small to ensure that one does not run out of memory. In a default MariaDB installation the default of most of the above Of simultaneous users that are executing queries that are using these If any variables in the last group is very large and you have a lot Used to store temporary tables in memory. Used by some storage engines when doing bulk insert Size of buffer to use when using multi-range read with range access Used when no keys can be used to find a row in next table Buffers and caches used during query execution:.Note that temporary blob storage is not included in the memory information in information_schema.processlist but only in the total memory used ( show global status like "memory_used"). Some storage engine will keep a temporary cache to store the largest blob seen so far when scanning a table.( myisam_sort_buffer_size, aria_sort_buffer_size).

Internal ones used during engine index creation.

Local buffers that are allocated on demand whenever needed.

Global caches onces that grow and shrink dynamically on demand up to max limit:.

Storage engine buffers ( innodb_buffer_pool_size, key_buffer_size, aria_pagecache_buffer_size, etc).

Global ones that are only allocated once during the lifetime of the server:.

There are two kind of buffers in MariaDB: If the MariaDB server is crashing because of 'out-of-memory' then it is probably wrongly configured. If you have a tiny antique, or a tiny VM, then those percentages are too high.

The 20%/70% assumes you have at least 4GB of RAM. Be sure the changes are under the section, not some other section.Don't change anything else unless you run into trouble (eg, max connections).Don't get carried away with the query cache until you understand what it can and cannot do.

Slow queries can usually be 'fixed' via indexes, schema changes, or SELECT changes, not by tuning.

Change key_buffer_size and innodb_buffer_pool_size according to engine usage and RAM.

Start with released copy of my.cnf / my.ini.

(Plus key_buffer_size = 10M, small, but not zero.) If only using InnoDB, set innodb_buffer_pool_size to 70% of available RAM. If only using MyISAM, set key_buffer_size to 20% of available RAM.
