Get started with Quickstart Guide for Percona Server for MySQL.

Percona Server for MySQL 8.0.39-30 includes all the features and bug fixes available in the MySQL 8.0.38 Community Edition and MySQL 8.0.39 Community Edition and enterprise-grade features developed by Percona.

Release highlights

Improvements and bug fixes provided by Oracle for MySQL 8.0.38, MySQL 8.0.39 and included in Percona Server for MySQL are the following:

  • The server could not restart successfully after creating a large number of tables (8001 or more). This issue, Bug #36808732, is a regression of Bug #33398681.

  • Enhanced performance of tablespace file scanning during startup. (Bug #110402, Bug #35200385)

  • InnoDB file system operations now consistently perform an fsync on the parent directory when carrying out directory-altering tasks. (Bug #36174938)

  • Worker jobs now include details about the relay log file that initiated the transaction, rather than relying on the default specified by relay_log.

Find the complete list of bug fixes and changes in the MySQL 8.0.38 Release Notes and MySQL 8.0.39 Release Notes.

Improvements

  • PS-9233: Adds the UUID_VX component which provides a set of functions for generating and working with various versions of the Universally Unique Identifier (UUID).

Bug fixes

  • PS-8057: The variable slow_query_log_file at runtime did not match the value defined in the my.cnf file.

  • PS-9214: An ALTER TABLE operation that rebuilt an InnoDB table using the INPLACE algorithm could occasionally fail with an unwarranted duplicate primary key error. This could happen if there were concurrent insertions, even though theose insertions did not cause any primary key conflict.

  • PS-9314: There was no connection to the server because mysqld received signal 11 when using JSON_TABLE.

  • PS-9286: The Key Management Interoperability Protocol (KMIP) component left keys in a pre-active state.

  • PS-9306: MySQL versions 8.0.38, 8.4.1, and 9.0.0 exited upon restarting if the database contained 10,000 or more tables.

  • PS-9322: When super_read_only=1 is enabled, undo truncation couldn’t update the data dictionary (DD), resulting in orphaned truncate log files.

  • PS-9379: On some platforms, using the -l atomic flag could cause a compilation error because the compiler already has built-in support for atomic operations and does not require linking to the atomic library.

  • PS-9144: In-place ALTER TABLE operations that internally rebuilt tables sometimes resulted in lost rows if a concurrent purge happened.
