Future InnoDB File Formats

Looking into InnoDB docs I found list of names of future InnoDB file formats: Antelope, Barracuda, Cheetah, Dragon, Elk, Fox, Gazelle, Hornet, Impala, Jaguar, Kangaroo, Leopard, Moose, Nautilus, Ocelot, Porpoise, Quail, Rabbit, Shark, Tiger, Urchin, Viper, Whale, X, Y and Zebra.

Aren’t there animals starting on X and Y?

    Indeed, Peter, the early adopter documentation and code (which is very slightly newer than what you tested) did incorporate Xenops and Yak!

    Besides, Gazelles are fast and beautiful. Gnus … well …

    /* List of animal names representing file format. */
    const char* file_format_name_map[] = {

    I’ve asked Jay to change to show MySQL Performance Blog instead of Peter Zaitsev.

    You also can report the bug if it does not passes author information from original feed – there are a lot of blogs by multiple authors.
