------------------------------------
Summary: 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
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.
