------------------------------------

             Summary: Add MIN / MAX aggregations function for BOOLEAN types
                 Key: FLINK-3936
                 URL: https://issues.apache.org/jira/browse/FLINK-3936
             Project: Flink
          Issue Type: Improvement
          Components: Table API
    Affects Versions: 1.1.0
            Reporter: Fabian Hueske
             Fix For: 1.1.0


When executing TPC-H Q4, I observed that Calcite generates a MIN aggregate on Boolean literals
to translate a decorrelate subquery in an {{EXIST}} predicate.

MIN and MAX aggregates on Boolean data types are currently not supported and should be added.
