    Description

      Run optimizer tests on tables with system versioning, at least InnoDB and MyISAM, if there is time, then also Aria and RocksDB:

      • "traditional" optimizer tests for crashes;
      • transformation tests with most common transformers;
      • result comparison between versioned and not versioned tables on the same branch/revision;
      • CTE tests (see MDEV-14820, probably need to wait till it's fixed);
      • Window functions;
      • anything else you can think of in context of optimizer;

      Nice to do:

      • poor man's rough optimizer performance comparison for versioned vs non-versioned tables, see for example lib/GenTest/Validator/ExecutionTimeComparator.pm
