huyuanfeng2018 opened a new pull request, #11557:
URL: https://github.com/apache/iceberg/pull/11557
## background
When I configure distribution-mode=RANGE in the flink task, the task can
process the data as expected, but the processing speed is insufficient. Like
#7393, there is a serialization problem.
