Percona Distribution for MySQL 8.0.30 (PS-based variant)

Percona Distribution for MySQL 8.0.30 (PS-based variant) was released on November 29, 2022. It 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 8.0.30-22.

Improvements and bug fixes introduced by Oracle for MySQL 8.0.30 and included in Percona Server for MySQL are the following:

  • Support of Generated Invisible Primary Keys(GIPK). This feature automatically adds a primary key to InnoDB tables without a primary key. The generated key is always named my_row_id. The GIPK feature is not enabled by default. Enable the feature by setting sql_generate_invisible_primary_key to ON.
  • Added two new settings to the InnoDB_doublewrite system:
  • DETECT_ONLY. This setting allows only metadata to be written to the doublewrite buffer. Database page content is not written to the buffer. Recovery does not use the buffer to fix incomplete page writes. Use this setting only when you need to detect incomplete page writes.
  • DETECT_AND_RECOVER. This setting is equivalent to the current ON setting. The doublewrite buffer is enabled. Database page content is written to the buffer and the buffer is accessed to fix incomplete page writes during recovery.
  • The -skip_host_cache server option is deprecated and will be removed in a future release. Use SET GLOBAL host_cache_size= 0 or set host_cache_size = 0.
