----------------------------------

             Summary: Introduce runtime interfaces for specifying SSG-based resource requirements
                 Key: FLINK-21269
                 URL: https://issues.apache.org/jira/browse/FLINK-21269
             Project: Flink
          Issue Type: Sub-task
          Components: Runtime / Configuration
            Reporter: Yangze Guo
             Fix For: 1.13.0


As the entrypoint of the unified runtime, StreamGraphGenerator takes Transformations and various settings from user development APIs, and generates StreamGraph accordingly.

We propose to add StreamGraphGenerator#setSlotSharingGroupResource interface for specifying fine-grained resource requirements for SSGs.

The specified SSG resource requirements need to be passed on all the way to the corresponding SlotSharingGroup in ExecutionGraph.
