    Percona XtraBackup 8.0.33-28 (2023-07-19)¶

    Percona XtraBackup (PXB) is a 100% open source backup solution for all versions of Percona Server for MySQL and MySQL® that performs online non-blocking, tightly compressed, highly secure full backups on transactional systems. Maintain fully available applications during planned maintenance windows with Percona XtraBackup.

    Release highlights¶

    This release includes improvements, features, and bug fixes. Percona has implemented a two-stage release process for each version. The first release primarily ensures compatibility with the latest MySQL version, to help those customers who need an updated version of Percona XtraBackup as soon as possible. The second release contains additional bug fixes and any improvements or new features.

    Percona XtraBackup 8.0.33-28 implements a new data sink that uses the first in, first out (FIF0) method. With the FIFO data sink feature, users with a streaming capacity of 10Gbps (typically on a Local Area Network (LAN)) can benefit from faster backups by streaming data in parallel to object storage. This feature is in tech preview.

    Percona XtraBackup 8.0.33-28 implements the Dictionary cache feature. Dictionary cache improves the performance of xtrabackup --prepare operation.

    New feature¶

    PXB-2514: Implements a new data sink that uses FIFO (named pipes).

    Improvements¶

    • PXB-2955: Implements dictionary cache.

    • PXB-3033: Executes STOP SLAVE conditionally depending on --[lock-ddl].

    • PXB-3066: Fixes compilation issues on Debian 12.

    • PXB-2993: Makes Percona XtraBackup compatible with procps-4.

    Bug fix¶

    • PXB-2811: Fix for several Percona XtraBackup compilation warnings.

    • PXB-3075: Percona XtraBackup 8.0.33 could not prepare backups from 8.0.29 and previous versions.

    Packaging notes¶

    Percona XtraBackup 8.0.33-28 supports Debian 12.
