             Summary: Partition reuse does not take effect on edges of hybrid selective type
                 Key: FLINK-30902
                 URL: https://issues.apache.org/jira/browse/FLINK-30902
             Project: Flink
          Issue Type: Bug
          Components: Runtime / Coordination
    Affects Versions: 1.17.0
            Reporter: Weijie Guo
            Assignee: Weijie Guo
             Fix For: 1.17.0


Partition reuse only take effect for re-consumable edge, but hybrid selective result partition is not re-consumable. This optimization is very important to reduce the cost of the shuffle write phase. In the previous implementation, we will only force the broadcast edge to be of hybrid full(re-consumable) in the 'ResultPartitionTypeFactory'. As a result, for ALL_ EXCHANGE_HYBRID_SELECTIVE job, partition reuse cannot take effect for non-broadcast edges.
In fact, we expected to replace all the edges that can be reused with hybrid full result partition.
