Description: The ‘InnoDB_max_dirty_pages_pct’ parameter is a crucial configuration in the InnoDB storage engine of MySQL, defining the maximum percentage of dirty pages that can exist in the buffer pool. Dirty pages are those that have been modified in memory but have not yet been written to disk. This parameter allows database administrators to manage memory and system performance more efficiently. By setting a limit on the percentage of dirty pages, it can prevent the system from consuming too much memory, which could lead to poor performance or excessive resource usage. By default, this value is set to 75%, meaning that up to 75% of the buffer pool can be composed of dirty pages. If this limit is exceeded, InnoDB will begin writing dirty pages to disk to free up space and maintain performance. Proper configuration of this parameter is essential for optimizing transaction performance and ensuring data integrity, especially in high-load environments where write operations are frequent.
