Alexander Fedulov commented on FLINK-35240:
-------------------------------------------
I don't think touching any of the flush-specific properties should be
necessary. You can see in the FlameGraph that flush calls are due to close
being called and, as [~robyoung] mentioned, this is what
JsonGenerator.Feature#AUTO_CLOSE_TARGET is there for.
> Disable FLUSH_AFTER_WRITE_VALUE to avoid flush per record

> *Analysis：*
> * `org.apache.flink.formats.csv.CsvBulkWriter#addElement` will flush per
> record.
> *Solution：*
> * I think maybe we can disable `FLUSH_AFTER_WRITE_VALUE` to avoid flush when
> a record added.
