Zhu Zhu created FLINK-21734: ------------------------------- Summary: Allow BLOCKING result partition to be individually consumable Key: FLINK-21734 URL: https://issues.apache.org/jira/browse/FLINK-21734 Project: Flink Issue Type: Improvement Components: Runtime / Coordination Affects Versions: 1.13.0 Reporter: Zhu Zhu
Currently a BLOCKING result partition is consumable only when all the partitions of the corresponding IntermediateResult become consumable. This is an unnecessary complication and has caused some problems (FLINK-21707). Therefore I propose to simplify it to let BLOCKING result partitions be consumable individually. Note that this will result in the scheduling to become execution-vertex-wise instead of stage-wise, with a nice side effect towards better resource utilization. The PipelinedRegionSchedulingStrategy can be simplified along with change to get rid of the {{correlatedResultPartitions}}. -- This message was sent by Atlassian Jira (v8.3.4#803005)
