> There is at least one problem on planning: for some reason {{IgniteValues}}
> nodes have {{single}} distribution instead of {{broadcast}}, and
> {{IgniteExchange}} to affinity distribution is produced instead of
> {{IgniteTrimExchange}}.
> But even with {{IgniteExchange}} results should be correct. There is some
> another problem on mapping: fragment with {{IgniteValues}} is not sent to any
> node, so the result is empty.
