Syntax

Information Schema

EXPLAIN

  • EXPLAIN used to show incorrect information about how the optimizer resolved ORDER BY clause or Distinct. This was a long-standing problem with roots back in MySQL. Now, after MDEV-8646 and related fixes, the problem doesn't exist anymore. (For test cases, see MDEV-7982, MDEV-8857, MDEV-7885, MDEV-326)

Optimizations

  • Connection setup was made faster by moving creation of THD to new thread (MDEV-6150)

Compatibility

Variables

For a list of all new variables, see System Variables Added in MariaDB 10.2 and Status Variables Added in MariaDB 10.2. These include:

Scripts

Code

  • "fast mutexes" have been removed. These aren't faster than normal mutexes, and have been disabled by default for years - MDEV-8111.
