ifndef-SleePy opened a new pull request #9000: [FLINK-13101][datastream] Add slotSharingAfterChainingDisabled proper… URL: https://github.com/apache/flink/pull/9000 …ty of StreamGraph ## What is the purpose of the change * The reason of introducing it is to satisfy the requirement of Blink batch planner. * Because the current scheduling strategy is a bit simple. It can not support some complex scenarios, like a batch job with resources limited. * To be honest, it's probably a work-around solution. However it's an internal implementation, we can replace it when we are able to support batch job by scheduling strategy. * **This is alternative solution of FLINK-13101** ## Brief change log * Add a property `slotSharingAfterChainingDisabled` of `StreamGraph` * The property means, if there are some operators that can not be chained, disable slot sharing and translate these edges into `BLOCKING` result partition type. ## 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, Yarn/Mesos, ZooKeeper: no - The S3 file system connector: no ## Documentation - Does this pull request introduce a new feature? **yes** - If yes, how is the feature documented? **JavaDocs**
