HomeDatabaseMysql TutorialMySQL 5.6之innodb导入的改进

在MySQL 5.6之前,导入单个innodb表的idb文件需要对齐tablespace id,而如果tablespace id不一致,就需要通过在新库不挺的新建表

在MySQL 5.6之前,导入单个innodb表的idb文件需要对齐tablespace id,而如果tablespace id不一致,就需要通过在新库不挺的新建表,来增长tablespace id,,以致对齐tablespace id。

5.6版本之后

alter table ... import tablespace

已经不需要对齐tablespace id。

alter table ...for export

5.6增加了以上命令,可以使导出的idb文件保持一致状态,并且生成文件.cfg后缀文件。当我们需要单表复制的时候,直接拷贝.frm/.idb/.cfg文件,然后直接执行

alter table ... import tablespace

即可导入.

在5.6.8之后,可以不需要生成cfg文件,直接复制idb文件和结构文件即可进行导入!但是会生成如下告警:

Warning Code : 1810

InnoDB: IO Read error: (2, No such file or directory) Error opening './test/log_table_cube.cfg', will attempt to import without schema verification

注意,当对表加上for export锁定之后,复制完记得unlock tables释放该锁!

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.
