Release highlights

Percona XtraDB Cluster is based on Percona Server for MySQL. Find a complete list of improvements and bug fixes in the Percona Server for MySQL 8.0.39-30 (2024-10-08) release notes.

The release also installs Percona Telemetry. Find more information in the Telemetry on Percona XtraDB Cluster document.

Improvements and bug fixes provided by Oracle for MySQL 8.0.38 and 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.

Bug fixes

  • PXC-4452: The slow_query_log_file has a default value if applied in conjunction with max_slowlog_size.

  • PXC-4495: A Percona XtraDB Cluster node suddenly began accumulating on-demand cache files. The cache pool grows until the disk is full.

  • PXC-4500: A Percona XtraDB Cluster enters a broken state after a failed node restart.

  • PXC-4521: Percona Telemetry creates a dedicated, internal user limited to only collecting metrics. The user is created automatically when Percona Telemetry is enabled. If Percona Telemetry is disabled, the user is dropped during server startup.
