| Description |
|
The purpose of the InnoDB buffer pool dump is to allow InnoDB to be restarted with the same persistent data pages in the buffer pool. The InnoDB temporary tablespace that was introduced in MariaDB 10.2.2 is always reinitialized on restart. Therefore, it does not make sense to attempt to dump or restore any pages of the temporary tablespace. |
