    Get a value from a db, using a uri in the form of sdb://<profile>/<key>. If
    the uri provided does not start with sdb://, then it will be returned as-is.

    CLI Example:

    .. code-block:: bash

        salt-run sdb.get sdb://mymemcached/foo
    '''
    return salt.utils.sdb.sdb_get(uri, __opts__, __utils__)

    Set a value in a db, using a uri in the form of ``sdb://<profile>/<key>``.
    If the uri provided does not start with ``sdb://`` or the value is not
    successfully set, return ``False``.

    CLI Example:

    .. code-block:: bash

        salt-run sdb.set sdb://mymemcached/foo bar

    Perform a one-time generation of a hash and write it to sdb.

        surround the call with single quotes.
