> CALCITE-2812 introduced recursive queries in Calcite via the new operator RepeatUnion.
> However, this initial implementation was not complete, since it only provided RepeatUnion ALL (i.e. duplicates were returned).
> The current ticket aims to implement the missing feature:  RepeatUnion non-ALL (i.e. duplicates must be discarded).
