Improvements¶
Implementations inherited from the Innovation releases¶
- PXB-3155: The Percona Server for MySQL 8.0 series implemented the keyring_vault plugin. In the Innovation series and 8.4 version, the server shifts to a component infrastructure, the keyring’s functionality remains the same. Percona XtraBackup 8.4.0-1 supports the
keyring_vaultcomponent. Users can back up their encrypted data after they convert from thekeyring_vaultplugin to thekeyring_vaultcomponent.
Bug fixes¶
