Class BroadcastRecordWriter<T extends org.apache.flink.core.io.IOReadableWritable>

java.lang.Object

org.apache.flink.runtime.io.network.api.writer.RecordWriter<T>

org.apache.flink.runtime.io.network.api.writer.BroadcastRecordWriter<T>

Type Parameters:

T - the type of the record that can be emitted with this record writer

public class BroadcastRecordWriter<T extends org.apache.flink.core.io.IOReadableWritable>
extends RecordWriter<T>

A special record-oriented runtime result writer only for broadcast mode.

The BroadcastRecordWriter extends the RecordWriter and handles emit(IOReadableWritable) operation via RecordWriter.broadcastEmit(IOReadableWritable) directly in a more efficient way.
