> Let some scheduler components updatable
> ---------------------------------------
>
> Key: FLINK-25033
> URL: https://issues.apache.org/jira/browse/FLINK-25033
> Project: Flink
> Issue Type: Sub-task
> Components: Runtime / Coordination
> Reporter: Lijie Wang
> Assignee: Lijie Wang
> Priority: Major
>
> Many scheduler components rely on the execution topology to make decisions.
> Some of them will build up some mappings against the execution topology on
> initialization for later use. When the execution topology becomes dynamic,
> these components need to be notified about the topology changes and adjust
> themselves accordingly. These components are:
> * DefaultExecutionTopology
> * SchedulingStrategy
> * PartitionReleaseStrategy
> * SlotSharingStrategy
> * OperatorCoordinatorHandler
> * Network memory of SlotSharingGroup.
