Implemented Features

Syntax / General Features




  • Temporary files created by merge sort and row log are encrypted if innodb_encrypt_log is set to 1, regardless of whether the table encrypted or not (MDEV-12634).



Global-transaction ID

  • New system variable gtid_pos_auto_engines for improving performance if a server is using multiple different storage engines in different transactions (MDEV-12179)

Data type API

10.3 continues refactoring for the data type API started in 10.2, which will make it possible to have user data type plugins. This work is still in progress (see MDEV-4912 for the current status and subtasks). Most of the task in this category do not change the server behavior. Some tasks do have a visible effect.

Idle transactions

Connections with idle transactions can be automatically killed after a specified time period by means of the idle_transaction_timeout, idle_readonly_transaction_timeout and idle_write_transaction_timeout system variables.

System Variables

For a list of all new variables, see System Variables Added in MariaDB 10.3 and Status Variables Added in MariaDB 10.3.
