Aljoscha Krettek commented on FLINK-2069:
-----------------------------------------
Yes, you are right but I think in the `CsvOutputFormat` the buffer is just used
because all the fields and field separates are written to the output stream
separately.
It still doesn't fix the bug that [~fobeligi] reported, however.
