    MySQL supports JSON as of version 5.7.  Note that MariaDB does **not**
    support JSON at the time of this writing.

    The :class:`.mysql.JSON` type supports persistence of JSON values
    as well as the core index operations provided by :class:`.types.JSON`
    datatype, by adapting the operations to render the ``JSON_EXTRACT``
    function at the database level.
