Percona Server for MySQL 8.0.28-20 introduces a new keyring component, component_keyring_kms, which allows using the AWS Key Management Service as a keyring. The component is also included in Percona XtraBackup 8.0.28, allowing backing up databases encrypted with this component.

The feature is similar to the AWS keyring plugin included in MySQL Enterprise, but it is implemented as a component instead, and because of that, it requires a different configuration.

Configuring AWS KMS

The component uses a single Master Key on KMS, which has to be created manually before configuring the component. This key can also be changed later, and existing keys using the old key will remain usable, as long as the key still exists …

This includes calculating digests (with a great variety of hash functions), asymmetric key generation (RSA, …

When performing physical backup on system that are heavily used, it can happen that the backup speed cannot keep up with the redo log generation. This can happen when the backup storage is slower than the redo log storage media and this can lead in inconsistency in the generated backup.

MySQL Enterprise Backup (aka MEB) and probably Percona Xtrabackup, benefit from the possibility to sequentially write redo log records to an archive file in addition to the redo log files.

This feature was introduced in MySQL 8.0.17.

How to enable it ?

• set globally a directory where those archiving logs can be stored
• start the archiving process in a session by calling a dedicated function
