> Key: FLINK-28446
> URL: https://issues.apache.org/jira/browse/FLINK-28446
> Project: Flink
> Issue Type: Improvement
> Affects Versions: 1.16.0
> Reporter: Yuxin Tan
> Priority: Critical
> Labels: pull-request-available
>
> To improve shuffle performance, more detailed fields should be added to
> PartitionDescriptor, for example, whether the partition is a broadcast
> partition or the distribution pattern of the intermediate result.
> After the detailed information is added, the Shuffle Service can use
> different Shuffle strategies in different situations, which may lead to
> better shuffle performance.
> In addition, we only add fields to PartitionDescriptor, which is compatible
> with the previous version, and the added fields are insensitive to earlier
> users.
