Timo Walther commented on FLINK-9964:
-------------------------------------
We had a discussion recently where somebody was asking for reading a CSV with
Avro schema (see FLINK-9813). We could think about a way of defining a schema
from a format schema. This would mean {{JSON schema -> table schema -> derived
Csv schema}}. But this is out of scope of this issue. Let's first focus on a
set of built-in formats.
> Add a CSV table format factory

> Key: FLINK-9964
> URL: https://issues.apache.org/jira/browse/FLINK-9964
> 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.
