Meant to message you and will do now before i forget again. We need a tiny tweak to randomize to make sure the storage specific subclass is loaded correctly, otherwise the dispatch table won’t work:

current:

sub _rand_order_by {
return $rand_order_by{ref shift->result_source->storage} || ‘RAND()’;
}

fixed

sub _rand_order_by {
my $self = shift @_;
$self->result_source->storage->ensure_connected;
return $rand_order_by{ref $self->result_source->storage} || ‘RAND()’;
}

Thanks! Let me know if you want a ‘real’ patch (feel free to point me at github or something.)
