类 CompressedBlockChannelWriter

java.lang.Object

org.apache.flink.table.runtime.io.CompressedBlockChannelWriter

所有已实现的接口:

org.apache.flink.runtime.io.disk.iomanager.BlockChannelWriter<org.apache.flink.core.memory.MemorySegment>, org.apache.flink.runtime.io.disk.iomanager.BlockChannelWriterWithCallback<org.apache.flink.core.memory.MemorySegment>, org.apache.flink.runtime.io.disk.iomanager.FileIOChannel, org.apache.flink.runtime.io.network.buffer.BufferRecycler

public class CompressedBlockChannelWriter
extends Object
implements org.apache.flink.runtime.io.disk.iomanager.BlockChannelWriter<org.apache.flink.core.memory.MemorySegment>, org.apache.flink.runtime.io.network.buffer.BufferRecycler

Compressed block channel writer provides a scenario where MemorySegment must be maintained.
