类 StateChangelogHandleStreamHandleReader

java.lang.Object

org.apache.flink.runtime.state.changelog.StateChangelogHandleStreamHandleReader

所有已实现的接口:

StateChangelogHandleReader<ChangelogStateHandleStreamImpl>

@Internal
public class StateChangelogHandleStreamHandleReader
extends Object
implements StateChangelogHandleReader<ChangelogStateHandleStreamImpl>

A reader for ChangelogStateHandleStreamImpl that iterates over its underlying stream handles and offsets. Starting from each offset, it enumerates the state changes using the provided StateChangelogHandleStreamHandleReader.StateChangeIterator. Different StateChangelogStorage implementations may have different iterator implementations. Using a different ChangelogStateHandle (and reader) is problematic as it needs to be serialized.
