protected AsynchronousBlockWriterWithCallback(FileIOChannel.ID channelID, RequestQueue<org.apache.flink.runtime.io.disk.iomanager.WriteRequest> requestQueue, RequestDoneCallback<MemorySegment> callback) throws IOException
channelID- The ID of the channel to write to.
requestQueue- The request queue of the asynchronous writer thread, to which the I/O requests are added.
callback- The callback to be invoked when requests are done.
IOException- Thrown, if the underlying file channel could not be opened exclusively.
public void writeBlock(MemorySegment segment) throws IOException
segment- The segment to be written.
IOException- Thrown, when the writer encounters an I/O error. Due to the asynchronous nature of the writer, the exception thrown here may have been caused by an earlier write request.
