> Project: Flink
> Issue Type: Improvement
> Components: Flink CDC
> Affects Versions: cdc-3.2.0
> Reporter: LvYanquan
> Priority: Critical
> Labels: pull-request-available
> Fix For: cdc-3.2.0
>
>
> Currently, Kafka Pipeline Sink partition events by
> parallelInstanceId % partitions.length，this is because the previous partition
> operator has already shuffled events by key.
> However, If the parallelism of the task is modified and restarted, data with
> the same key before and after the task may be in different partitions.
