> Registering as table source streams with Row is currently not possible:
> Java:
> DataStream<Row> ds = ...
> tableEnv.registerDataStream("MyTableRow", ds, "a, b, c ...");
> org.apache.flink.table.api.TableException: Source of type Row(f0: Integer,
> f1: Long, f2: Integer, f3: String, f4: Integer) cannot be converted into
> Table.

> org.apache.flink.table.api.TableEnvironment.getFieldInfo(TableEnvironment.scala:680)

> org.apache.flink.table.api.StreamTableEnvironment.registerDataStreamInternal(StreamTableEnvironment.scala:363)

> at
> org.apache.flink.table.api.java.stream.sql.SqlITCase.testRow2(SqlITCase.java:92)
> Scala:
> val ds:DataStream[Row] = ...
> tableEnv.registerDataStream("MyTableRow", ds, "a, b, c, d, e");
> org.apache.flink.api.java.typeutils.GenericTypeInfo cannot be cast to
> org.apache.flink.api.common.typeutils.CompositeType
> This can be supported by extending the in the
> org.apache.flink.table.api.TableEnvironment
> getFieldInfo()
> and by constructing the StreamTableSource correspondingly
