Is it possible to disable keys in InnoDB tables?

If yes, how?

If not, why?

I was under the impression InnoDB can have keys disabled and enabled. I just did some digging. It cannot be done. So, I was wrong.

Key constraints, however, can be turned on and off for a specific session:

  • If you have UNIQUE secondary indexes, you can try setting this to speed up INSERTs that are disk bound:
    SET unique_checks = 0;
  • To disable foreign key checks for a suggestion, use Randy Melder's suggestion:
    SET foreign_key_checks = 0;
