@Internal
public interface ChangelogStateBackendHandle
extends KeyedStateHandle
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).
