Weijie Guo created FLINK-29769: ---------------------------------- Summary: Further limit the explosion range of failover in hybrid shuffle mode Key: FLINK-29769 URL: https://issues.apache.org/jira/browse/FLINK-29769 Project: Flink Issue Type: Sub-task Components: Runtime / Coordination Affects Versions: 1.17.0 Reporter: Weijie Guo
Under the current failover strategy, if a region changes to the failed state, all its downstream regions must be restarted. For ALL_ EDGE_BLOCKING type jobs, since they are scheduled stage by state, no additional overhead. However, for the hybrid shuffle mode, the upstream and downstream can both run at the same time. If the upstream task fails, we hope that it will not affect the downstream regions that do not consume it. -- This message was sent by Atlassian Jira (v8.20.10#820010)
