DOAG Datenbank Konferenz 2016

Taxonomy upgrade extras: 

Heute war ich auf der DOAG Datenbank 2016 Konferenz in Düsseldorf. Der einzige Vortrag zum Thema MySQL war mein eigener: MySQL für Oracle DBAs. Daher hatte ich die Möglichkeit wieder mal etwas über den Zaun zu linsen. Hier meine Notizen:

Differences between MySQL and MariaDB

  • max_user_connections Can be changed online in MySQL. Cannot be changed in MariaDB if value was set to 0.
  • PERFORMANCE_SCHEMA is enabled in MySQL 5.6 and 5.7 by default. In MariaDB disabled by default.
  • Replication incompatibilities from MariaDB (Master) to MySQL (Slave)
  • MariaDB 10.2.0 still contains XtraDB 5.6. So MySQL 5.7 features cannot be used.
  • MariaDB 10.2 Window Functions are missing in MySQL 5.7
  • SHOW PROCESSLIST has additional column Progress in MariaDB.
