MySQL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:
- Insert时,分表和不分表的性能所差无几;
- 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;
- 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;
- 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;
- 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~~~
