类 ChangelogStateBackend

java.lang.Object

org.apache.flink.state.changelog.AbstractChangelogStateBackend

org.apache.flink.state.changelog.ChangelogStateBackend

所有已实现的接口:

Serializable, org.apache.flink.runtime.state.ConfigurableStateBackend, org.apache.flink.runtime.state.delegate.DelegatingStateBackend, org.apache.flink.runtime.state.StateBackend

@Internal
public class ChangelogStateBackend
extends AbstractChangelogStateBackend
implements org.apache.flink.runtime.state.ConfigurableStateBackend

This state backend holds the working state in the underlying delegatedStateBackend, and forwards state changes to State Changelog.
