> Components: Table API
> Affects Versions: 1.1.0
> Reporter: Fabian Hueske
> Assignee: 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.
