Notable Changes

Variables

InnoDB

Replication

  • Eliminate deadlock involving parallel workers, STOP SLAVE and FLUSH TABLES WITH READ LOCK (MDEV-23089)

Optimizer

  • ALTER TABLE ... ANALYZE PARTITION ... with EITS reads and locks all rows ... (MDEV-21472)
  • Print ranges in the optimizer trace created for non-indexed columns when optimizer_use_condition_selectivity >2 Now the optimizer trace shows the ranges constructed while getting estimates from EITS (MDEV-22665)
  • LATERAL DERIVED is not clearly visible in EXPLAIN FORMAT=JSON, make LATERAL DERIVED tables visible in EXPLAIN FORMAT=JSON output (MDEV-17568)
