1. query_cache_min_res_unit 是 MySQL 中控制查询缓存行为的关键参数。2. 该参数定义查询结果存储在缓存时,每次分配内存块的最小单元(默认为4KB)。3. 该值需要根据实际情况调整: - 过小的设定会增加内存碎片 - 过大的设定会浪费内存空间 - 具体计算公式:query_cache_min_res_unit = (query_cache_size - Qcache_...
残差组件Resunit 残差偏差 ###误差(Errors) 观测值与真实值的偏差。 这种真实值(true value)往往是不可观测的,比如用仪器去测量一个物体的长度,无论是采用简单的直尺,还是采用高精度的游标卡尺,亦或是螺旋测微器,都无法观测到直尺的真实长度。观测值只能无限靠近真实值,却无法等同于真实值,靠近真实值的远近,即...
