HomeDatabaseMysql TutorialMySQL分表(Partition)学习研究报告_MySQL

bitsCN.com

最近在开发一个新的项目,可能会产生大数据量,需要对部分表进行分表操作,故来研究学习MySQL的分表功能。

由于实验报告已经写成Exlce文件了,各位看过就直接下载吧:MySQL分表分析报告.xls

以下是此次实验的结论:

  1. Insert时,分表和不分表的性能所差无几;
  2. 大量数据Insert时,大量数据整合成一条Sql的性能比逐个Insert的性能提高很多;
  3. 分表与否并不影响查询操作,其返回的结果还是和不分表的是一样的;
  4. 实际数据的存储,并不是完全按照分表策略执行的,会存在一定的偏差;
  5. 查询如果不是针对分表属性的话,反而会稍微慢一点;但是按照查询字段进行分区的效果很明显;

如有纰漏错误,欢迎各位指教啊~~~

Explain the InnoDB Buffer Pool and its importance for performance.Explain the InnoDB Buffer Pool and its importance for performance.Apr 19, 2025 am 12:24 AM

InnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.
