> Key: FLINK-28799
> URL: https://issues.apache.org/jira/browse/FLINK-28799
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Coordination
> Affects Versions: 1.16.0
> Reporter: Weijie Guo
> Assignee: Weijie Guo
> Priority: Critical
> Labels: pull-request-available
> Fix For: 1.16.0

>
> Based on TPC-DS test, we found that hybrid shuffle can't schedule graph
> contains blocking edge. The reason is that some batch operators will forcibly
> set the exchange mode to blocking, which breaks ALL_ EDGE_HYBRID‘s constraint
> makes the scheduling deadlock.
> We should think of a better way to support the scheduling the graph of all
> kinds of edges, including hybrid edge.
