Aljoscha Krettek closed FLINK-9964.
-----------------------------------
Resolution: Fixed
Release Note:
This release introduces a new format descriptor for CSV files that is compliant
with RFC 4180. The new descriptor is available as
`org.apache.flink.table.descriptors.Csv`. For now, this can only be used
together with the Kafka connector. The old descriptor is availabla as
`org.apache.flink.table.descriptors.OldCsv` for use with file system connectors.
was:The descriptor o.a.f.table.descriptors.Csv does not describe Flink's old
non-standard CSV table source/sink anymore. Instead, it can be used when
writing to Kafka. The old one is still available under
"org.apache.flink.table.descriptors.OldCsv" for stream/batch filesystem
operations.

> We should add a RFC 4180 compliant CSV table format factory to read and write
> data into Kafka and other connectors. This requires a
> {{SerializationSchemaFactory}} and {{DeserializationSchemaFactory}}. How we
> want to represent all data types and nested types is still up for discussion.
> For example, we could flatten and deflatten nested types as it is done
> [here|http://support.gnip.com/articles/json2csv.html]. We can also have a
> look how tools such as the Avro to CSV tool perform the conversion.
