As of MySQL 5\&.7\&.12, the default

In MySQL 5\&.7\&.11, the default

|

|

InnoDB

|
keyring_file
|
|||
|
|
plugin to be loaded prior to
|
|||
|
|
InnoDB
|
|||
|
|
initialization, so this change of default value introduces an incompatibility for upgrades from 5\&.7\&.11 to 5\&.7\&.12 or higher\&. Administrators who have encrypted
|
|||
|
|
InnoDB
|

tablespaces must take explicit action to ensure continued loading of the
