Percona XtraDB Cluster 8.4.7-7 has been released

This release is based on Percona Server for MySQL 8.4.7-7.

Percona XtraDB Cluster 8.4.7-7

Announcement – Discontinuation of the Percona PRO Program

Percona has consolidated its build offerings. The Pro builds are no longer required. All features from the Percona Server for MySQL 8.4.x Pro build series and Percona XtraBackup 8.4.x Pro build series have been merged into the main open source Community release.

Starting with Percona XtraDB Cluster 8.4.7-7, the xtrabackup SST method uses the Reduced backup lock time feature. This enhancement minimizes blocking on the Donor node during SST process while the backup is being prepared. The Percona XtraBackup reduced lock feature is enabled by default. To modify this behavior, set the desired lock_ddl value in the [xtrabackup] section of the my.cnf configuration file. For more information about the --lock-ddl option and its available values, refer to the xtrabackup command-line options documentation.

Percona Server for MySQL 8.4.7-7

  • The audit log plugin has been reintroduced in Percona Server for MySQL 8.4. However, it is already marked as deprecated and is planned for removal in a future release. This deprecation is due to the availability of the audit log filter component, which is the recommended replacement. Users should migrate to this component, which provides equivalent functionality with enhanced flexibility, performance, and filtering capabilities, ensuring continued support for auditing and compliance requirements.

MySQL 8.4.7

Improvements and bug fixes provided by Oracle for MySQL 8.4.7 and included in Percona Server for MySQL are the following:

  • Fixed an issue that caused excessive memory chunk usage for very large buffer pools, which could lead to allocation failures. The allocation process now includes validation to ensure sufficient and stable memory allocation. (Bug #37994397)

  • Fixed an issue where assertion failures could occur due to data size and bounds mismatches during DDL file operations. (Bug #37882398)
