I can't tell you how many times over 20 years I've heard a DBA tell me "the statistics weren't updated" after an incident.

  This is my reason for preferring NOSQL where possible.

  I've written cron jobs to update mysql statistics to prevent it from choosing bad query plans. It's as terrible as it sounds.

    How come it's not automatic and built-in? Why is a script terrible? (Does it have to enumerate all tables and piecewise run the stat update?)

      Yes, the stats update is per table. We only updated it for a few tables we really cared about.
