-----------------------------------
Summary: Remove ClassTag in Scala DataSet API
Key: FLINK-7691
URL: https://issues.apache.org/jira/browse/FLINK-7691
Project: Flink
Issue Type: Improvement
Components: DataSet API
Reporter: Timo Walther
In the DataStream API a {{ClassTag}} is not required, which allows to pass
{{TypeInformation}} manually if required. In the DataSet API most methods look
like:
{code}
// DataSet API
def fromElements[T: ClassTag : TypeInformation](data: T*): DataSet[T]
// DataStream API
def fromElements[T: TypeInformation](data: T*): DataStream[T]
{code}
I would propose to remove the ClassTag, if possible. This would make it easier
e.g. to supply TypeInformation for the {{Row}} type. Or is there an easier way
in Scala that I don't know?
