[jira] [Comment Edited] (FLINK-9964) Add a CSV table format factory

[~twalthr] I've tried some tests on the Jackson library, and it looks good except that it cannot support nested Array values like *String[][].class*, but I think we should do what you just said at the first step.

> 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.
