- 10. Authentication - MySQL 8 A superuser account 'root'@'localhost is created. A password for the superuser is set and stored in the error log file. Single authentication method per user © 2020 Percona10
- 11. Authentication - MariaDB 10.4 Multiple Authentication Methods per Account The root user is created with both mysql_native_password and the unix_socket auth plugin. unix_socket matches your OS uid with a mysql user. mysql_native_password auth creates an “INVALID” password change with SET PASSWORD() classic approach. © 2020 Percona11

- 31. Conclusion - MySQL 8 ❖ 8.0.0 to 8.0.5 Several Bugs Fixed ❖ 8.0.11 Deprecates uft8mb3 ❖ 8.0.12 Improves performance_schema defaults ❖ 8.0.13 Major deprecations InnoDB, Partitioning ❖ 8.0.14 Dual passwords, Lateral Derived Tables, Parallel Read of Index , GR Consistency Levels ❖ 8.0.15 Bugs Fixed ➢ InnoDB: After a checkpoint operation persisted modifications to data dictionary metadata, there was potential for new metadata changes to be lost under certain circumstances. (Bug #29120297) ➢ Group Replication was unable to function in the 8.0.14 release of MySQL Server if IPv6 support was disabled at the operating system level, even if the replication group did not use any IPv6 addresses. The issue is fixed by this release of MySQL Server, 8.0.15. (Bug #29249542, Bug #94004) ❖ If MySQL was running on the host system and within Docker, it was not possible to update or remove MySQL on the host system. (Bug #28244773, Bug #91405)8.0.0 to 8.0.11 several bug fixes ❖ 8.0.16 Account-management capabilities, deprecation of mysql_upgrade, Check Constraints, GR Auto Re-Join ❖ 8.0.17 Clone Plugin, JSON Array Indexes and Schema ❖ 8.0.18 Hash Join, Explain Analyze 31 © 2020 Percona
- 32. Conclusion - MariaDB 10.4 Authentication The unix_socket authentication plugin is now default on Unix-like systems, which is a major change to authentication in MariaDB (MDEV-12484) ➢ User password expiry (MDEV-7597) ➢ Account Locking (MDEV-13095) ➢ ...more ❖ InnoDB Added instant DROP COLUMN and changing of the order of columns (MDEV-15562) More Instant VARCHAR extension or ROW_FORMAT=DYNAMIC and ROW_FORMAT=COMPACT (MDEV-15563) ➢ Reduced redo log volume for undo tablespace initialization (MDEV-17138) ➢ Removed crash-upgrade support for pre-10.2.19 TRUNCATE TABLE (MDEV-13564) ❖ Optimizer ➢ Implementation of the optimizer trace, one can enable the optimizer trace by enabling the system variable optimizer_trace (MDEV-6111) ❖ GaleraRef:https://mariadb.com/kb/en/library/changes-improvements-in-mariadb-104/ © 2020 Percona32
