接口 StateSnapshotContext

所有超级接口:

FunctionSnapshotContext, ManagedSnapshotContext

所有已知实现类:

StateSnapshotContextSynchronousImpl

@PublicEvolving
public interface StateSnapshotContext
extends FunctionSnapshotContext

This interface provides a context in which operators that use managed (i.e. state that is managed by state backends) or raw (i.e. the operator can write it's state streams) state can perform a snapshot.
