Jark Wu commented on FLINK-19868:
---------------------------------
I think {{csv.line-delimiter}} is not a good option for csv format, the
{{line-delimiter}} should be an option of filesystem, because it is never used
for message queues.
For the row-wise formats, it should consume and produce the bytes for a row.
The line splitting should be handled by connectors.
I also searched the mailing list, and I didn't find any user asking questions
about {{csv.line-delimiter}}, only some people are asking
{{csv.field-delimiter}}.
Therefore, I think we can remove {{csv.line-delimiter}} option (mention this in
release note) and not append a new line in {{CsvRowDataSerializationSchema}}.
What do you think?
