Percona Distribution for MySQL 8.0.29 using Percona Server for MySQL (2022-08-09)

Release date August 8, 2022
Installation Installing Percona Distribution for MySQL

Percona Distribution for MySQL is a single solution with the best and most critical enterprise components from the MySQL open-source community, designed and tested to work together.

Percona Distribution for MySQL provides two deployment variants: one is based on Percona Server for MySQL and another one is based on Percona XtraDB Cluster.

This release is focused on the Percona Server for MySQL-based deployment variant. It is based on Percona Server for MySQL 8.0.29-21.

Release Highlights

The following lists a number of the bug fixes for MySQL 8.0.29, provided by Oracle, and included in Percona Server for MySQL and Percona Distribution for MySQL:

  • The Performance Schema tracks if a query was processed on the PRIMARY engine, InnoDB, or a SECONDARY engine, HeatWave. An EXECUTION_ENGINE column, which indicates the engine used, was added to the Performance Schema statement event tables and the sys.processlist and the sys.x$processlist views.
  • Added support for the IF NOT EXISTS option for the CREATE FUNCTION, CREATE PROCEDURE, and CREATE TRIGGER statements.
  • An anonymous user with the PROCESS privilege was unable to select processlist table rows.

Percona Server for MySQL has changed the default for supported DDL column operations to ALGORITHM=INPLACE. This fixes corruption issue and several other issues with the INSTANT ADD/DROP COLUMN DDL (Find more details in PS-8292, PS-8291 and PS-8303).

In MySQL 8.0.29, the default setting for supported DDL operations is ALGORITHM=INSTANT. You can explicitly specify ALGORITHM=INSTANT in DDL column operations.

  • DISTMYSQL-198: orchestrator client packages were missing for RPM based distributions. Starting from v8.0.29 they are now built and available for download.
