In order to improve the performance of database operations, MySQL allocates buffers and caches memory. As a default, the MySQL server starts on a virtual machine (VM) with 512 MB of RAM. We can modify the default configuration for MySQL to run on limited memory systems.
The following list describes the ways to optimize MySQL memory:
- The memory area which holds cached InnoDB data for tables, indexes, and other auxiliary buffers is known as the InnoDB buffer pool. The buffer pool is divided into pages. The pages hold multiple rows. The buffer pool is implemented as a linked list of pages for efficient cache management. Rarely used data is removed from the cache using an algorithm. Buffer pool size is an important ...
