Percona XtraDB Cluster 8.0.43-34 is based on Percona Server for MySQL and contains all improvements and bug fixes available in Percona Server for MySQL 8.0.43-34.

Percona XtraDB Cluster 8.0.43-34

Percona Server for MySQL 8.0.43-34

Implements Link-Time Optimization (LTO) to generate more optimized release binaries, resulting in improved performance for specific workloads.

MySQL 8.0.43

Improvements and bug fixes provided by Oracle for MySQL 8.0.43 and included in Percona Server for MySQL are the following:

  • Fixed an issue where rebuilding a primary key with duplicate entries could cause the server to stop unexpectedly. (Bug #37822992)

  • Fixed an issue related to dropping columns that were part of an index. (Bug #37726881)

  • Fixed an issue with indexing spatial datatype columns. (Bug #36682518)

  • Fixed an issue where creating a secondary index on a VARCHAR column could exceed configured memory limits, with the amount allocated being directly related to the value of innodb_ddl_buffer_size, leading to errors such as ERROR 1136 (21S01): Column count doesn't match value count at row 1. (Bug #37233273)

Build & packaging notes

  • The official packages were built with the WITH_LTO=ON flag to enable the Link-Time Optimization (LTO) feature.
