[jira] [Created] (FLINK-25668) Support calcuate network memory for dynamic graph.

Lijie Wang created FLINK-25668:
----------------------------------

             Summary: Support calcuate network memory for dynamic graph.
                 Key: FLINK-25668
                 URL: https://issues.apache.org/jira/browse/FLINK-25668
             Project: Flink
          Issue Type: Sub-task
          Components: Runtime / Coordination
            Reporter: Lijie Wang


Currently, when fine-grained resource management is enabled, the scheduler will calculate network memory for all {*}SlotSharingGroup{*}s during its initialization.

For dynamic graphs, the network memory of *SlotSharingGroup* should also be calculated lazily. Once a vertex is initialized, find its corresponding slot sharing group and check whether all vertices in this slot sharing group have been initialized. If all vertices have been initialized, the scheduler will calculate the network resources for this slot sharing group.
