    Percona XtraBackup 8.0.27-19¶

    • Date

      February 2, 2022

    • Installation

      Installing Percona XtraBackup

    Percona XtraBackup enables MySQL backups without blocking user queries, making it ideal for companies with large data sets and mission-critical applications that cannot tolerate long periods of downtime. Offered free as an open source solution, it drives down backup costs while providing unique features for MySQL backups.

    Release Highlights¶

    The following list contains a number of the bug fixes for MySQL 8.0.27, provided by Oracle, and included in Percona Server for MySQL:

    • The default_authentication_plugin is deprecated. Support for this plugin may be removed in future versions. Use the authentication_policy variable.

    • The binary operator is deprecated. Support for this operator may be removed in future versions. Use CAST(... AS BINARY).

    • When a parent table updated or deleted a row, this operation initiated a cascading SET NULL operation on the child table. On the child table, a virtual column value could be set to NULL instead of the value derived from the base column value.

    Find the full list of bug fixes and changes in the MySQL 8.0.27 Release Notes.

    New Features¶

    • PXB-1883: Added support for Microsoft Azure Cloud Storage in the xbcloud binary. (Thanks to Ivan for reporting this issue)

    Improvements¶

    • PXB-2434: Use MySQL page tracking for incremental backup

    Bugs Fixed¶

    • PXB-1741: PS startup displays errors for databases excluded during partial backup

    • PXB-2614: The xbstream binary was enhanced to support sparse files on the XFS file system.

    • PXB-2608: Upgrade the Vault API to V2 (Thanks to Benedito Marques Magalhaes for reporting this issue)

    • PXB-2543: Fix that adds IB_EXPORT_CFG_VERSION_V6 when exporting a .cfg file for a table (Thanks to Peng Gao for reporting this issue)

    • PXB-2465: Fix for querying the ps.log_status when group replication channels are items on that list. XtraBackup skips the name if it matches either group_replication_applieror group_replication_recovery.(Thanks to Galamb Gergő for reporting this issue)

    • PXB-2625: The default version of CURL in Debian Buster failed to identify a TLS HTTP2 connection as closed and attempted to reuse the connection. (Thanks to Johan Andersson for reporting this issue)
