一、架构简要介绍

InnoDB的内存结构与磁盘结构

InnoDB architecture diagram showing in-memory and on-disk structures. In-memory structures include the buffer pool, adaptive hash index, change buffer, and log buffer. On-disk structures include tablespaces, redo logs, and doublewrite buffer files.

  • 内存结构(In-Memory Structures

    包括 buffer pool(缓存池)、change buffer(更改区缓存)、adaptive hash index(适应性哈希索引) 和 log buffer(日志缓存)

  • 磁盘结构(On-Disk Structures

    包括 tablespaces(表空间,包括 System tablespaceFile-Per-Table tablespacesGeneral tablespacesUnfo tablespaces、Temporary tablespaces)、redo logs(重做日志)、doublewrite buffer files(双写缓存文件)
