-------------------------------------

Thanks for working on this [~wind_ljy]. Let me know if you need help or want to discuss specifics. I'm working on better documentation for unified factories. This might also help you implementing this issue.

> 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.
