Review Comment:
@GOODBOY008 properly testing this behavior with a unit test might be tricky.
I wrote a quick sketch of an integration test that you could consider making
use of:
https://github.com/afedulov/flink/blob/fix-csv-flush-test/flink-formats/flink-csv/src/test/java/org/apache/flink/formats/csv/CsvBulkWriterTest.java
I did not spend much time coming up with proper assertions, you can surely
come up with something more elegant.
