Hi Artem,
I had a debug of Flink 1.17.1 (running CsvFilesystemBatchITCase) and I see
the same behaviour. It's the same on master too. Jackson flushes [1] the
underlying stream after every `writeValue` call. I experimented with
disabling the flush by disabling Jackson's FLUSH_PASSED_TO_STREAM [2]
I know that an `Object` is treated as a generic data type by Flink and

Hi,
Referring to

however they looked exactly the same.
Can include if necessary.
Thanks
Keith
