reswqa opened a new pull request, #21419: URL: https://github.com/apache/flink/pull/21419
## What is the purpose of the change *Hybrid full result partition is re-consumable now, and we have enabled `VertexwiseSchedulingStrategy` to support the scheduling of hybrid type edges in [FLINK-29767](https://issues.apache.org/jira/browse/FLINK-29767). Now is the time to enable hybrid full result partition to support speculative execution. In the case of speculative execution, downstream task can be scheduled only if all upstream task finished. In the next ticket, we will introduce a new mechanism to enable the downstream to be scheduled after partial upstream task is finished, thus improving the performance.* ## Brief change log - *Speculatvie execution vertex supports mark hybrid full result partition finished.* - *Introduce AllFinishedInputConsumableDecider.* - *Speculative scheduler supports hybrid full result partition.* ## Verifying this change This change added unit tests. ## Does this pull request potentially affect one of the following parts: - Dependencies (does it add or upgrade a dependency): no - The public API, i.e., is any changed class annotated with `@Public(Evolving)`: no - The serializers: no - The runtime per-record code paths (performance sensitive): no - Anything that affects deployment or recovery: JobManager (and its components), Checkpointing, Kubernetes/Yarn, ZooKeeper: yes - The S3 file system connector: no ## Documentation - Does this pull request introduce a new feature? no -- This is an automated message from the Apache Git Service.
