=head2 _set_updater

    Set a push updater into the store.

    This function only changes the local store. Use set_optimizer for
    multi-machines.

    Parameters
    ----------
    updater : function
        the updater function

    Examples
    --------
    >>> my $update = sub { my ($key, input, stored) = @_;
