--------------------------------
[~twalthr] Should we support json schema for csv format?
If json schema is needed in csv format, we may need to write a duplicate
converter like JsonRowSchemaConverter unless we import flink-json module, which
is inappropriate.
> Add a CSV table format factory

> Project: Flink
> Issue Type: Sub-task
> Components: Table API & SQL
> Reporter: Timo Walther
> Assignee: buptljy
> Priority: Major
>
> 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.
