    Description

      Extend join/aggregate materialized rewriting rule to produce rewritings using Union operators, e.g., a given query could be partially answered from the MV (year = 2014) and from the query (not(year=2014)). If the MV is stored e.g. in Druid, this rewriting might be beneficial. As with the other rewritings, decision on whether to finally use the rewriting is cost-based.
