> Add checks for unsupported operations in streaming table API
> ------------------------------------------------------------
>
> Key: FLINK-3794
> URL: https://issues.apache.org/jira/browse/FLINK-3794
> Project: Flink
> Issue Type: Improvement
> Components: Table API
> Affects Versions: 1.1.0
> Reporter: Vasia Kalavri
> Assignee: Vasia Kalavri
>
> Unsupported operations on streaming tables currently fail during plan
> translation. It would be nicer to add checks in the Table API methods and
> fail with an informative message that the operation is not supported. The
> operations that are not currently supported are:
> - aggregations inside select
> - groupBy
> - distinct
> - join
> We can simply check if the Table's environment is a streaming environment and
> throw an unsupported operation exception.
