    Description

      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).
