可以简单的把它理解成是 innodb_buffer_pool_size增加或缩小最小单位。 innodb_buffer_pool_size是有一个或多个 innodb_buffer_pool_chunk_size组成的。如果修改了 innodb_buffer_pool_chunk_size的值将会导致 innodb_buffer_pool_size的值改变。在修改该参数的时候，需要计算好最后的 innodb_buffer_pool_size是否...
innodb_buffer_pool_size是 InnoDB 存储引擎的一个重要配置项,指定了用于缓存数据页和索引页的 memória 量。该参数的设置决定了读取和写入操作的性能。 通过计算我们可以得到具体的内存分配推荐: [ \text{Recommended Size} = \text{Total RAM} \times 0.70 ] 调试步骤 为了找到与 CPU 使用率相关的具体问题,动态...

在一台总物理内存125G的服务器上,修改mysql的innodb_buffer_pool_size为64G后,启动报错,截图如下: 错误原因大致是内存不足。 诊断 开始以为是调优参数设置问题,仔细参阅官网后,未发现任何问题;试着将innodb_buffer_pool_size调整为60G,数据库可以正常启动,因此怀疑是操作系统限制了内存分配。通过排查发现该操作系统的...
The buffer pool extension feature extends the buffer pool cache with nonvolatile storage (usually SSD). Because of this extension, the buffer pool can accommodate a larger database working set, which forces the paging of I/Os between RAM and the SSDs. This effectively offloads small random I...
