Hi Anton,
I would also support the idea of moving Row and RowTypeInfo to Flink
core. I think there are many real-world use cases where a
variable-length record that supports null values is required. However, I
think that those classes needs to be reworked before. They should not
depend on Scala-related things.
RowTypeInfo should not inherit from CaseClassTypeInfo, the current
solution with the dummy field names is a hacky solution anyway. Row
should not inherit from Scala classes.
Regards,
Timo

Hello,
In Scala case classes can store huge count of fields, it's really helpful for
reading wide csv files, but It uses only in table api.
what about this issue (https://issues.apache.org/jira/browse/FLINK-2186),
should we use table api in machine learning library?
To solve the issue #readCsvFile can generate RowInputFormat.
For commodity I added another one constructor in RowTypeInfo
(https://github.com/apache/flink/compare/master...tonycox:FLINK-2186-x)
What do you think about add some scala and moving Row to Flink core?
