Information Schema

EXPLAIN

  • EXPLAIN FORMAT=JSON now shows outer_ref_condition field which contains the condition that the(?) SELECT checks on each re-execution - MDEV-9 — Original code from Galina Shalygina652.
  • EXPLAN FORMAT=JSON now shows sort_key field which shows the sort criteria used by filesort operation. (commit 2078392)
  • 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)
