> Issue Type: Improvement
> Components: Table API & SQL
> Reporter: Timo Walther
> Assignee: Anton Mushin

> Currently, the Table API is unable to count or sum up 0 elements. We should
> improve DataSet aggregations for this. Maybe by union the original DataSet
> with a dummy record or by using a MapPartition function. Coming up with a
> good design for this is also part of this issue.
