接口 ChangelogStateBackendHandle

所有超级接口:

CheckpointBoundKeyedStateHandle, CompositeStateHandle, KeyedStateHandle, Serializable, StateObject

所有已知实现类:

ChangelogStateBackendHandle.ChangelogStateBackendHandleImpl, ChangelogStateBackendLocalHandle

@Internal
public interface ChangelogStateBackendHandle
extends KeyedStateHandle, CheckpointBoundKeyedStateHandle

A handle to ChangelogStateBackend state. Consists of the base and delta parts. Base part references materialized state (e.g. SST files), while delta part references state changes that were not not materialized at the time of the snapshot. Both are potentially empty lists as there can be no state or multiple states (e.g. after rescaling).
