首先来看system tablespace的创建,在InnoDB中每一个tablespace都会有一个uint32类型的id,每一个唯一的id用来表示对应的tablespace,而system tablespace的space id就是0. static const space_id_t TRX_SYS_SPACE = 0; 而由于只有system tablespace和temporary tablespace是共享的,因此他们在InnoDB中有专门的数据结构来表示...

14.4.5 System Tablespace 系统表空间 InnoDB 系统表空间包含InnoDB 数据目录(元数据 用于InnoDB相关对象)和是存储区域用于doublewrite buffer, the change buffer, and undo logs. 系统表空间也包含表和索引数据用于任何用户创建的表,创建在系统表空间。
To complement the encryption of the system tablespace, it is also possible to encrypt the parallel doublewrite buffer using innodb_parallel_dblwr_encrypt, a feature unique to Percona Server for MySQL. This means that any data for an encrypted tablespace is also only written in an encrypted form...
A Tablespace file in InnoDB is made of multiple logical (and physical) pages where page 0 is called the tablespace header page. Page 0 keeps the metadata information (like FLAGS etc.) for the tablespace. Encryption information (tablespace key) is also kept on page0. Page 0 is NEVER encrypt...
If you are not usinginnodb_file_per_table, then all of the table data is stored in system tablespace. If you drop a table, the space is not reclaimed. You can shrink the system tablespace and reclaim the disk space. This requires a major downtime, so it is recommended to perform t...
