    checkArgument(closed);
    if (booleanOutputStream == null) {
        return Optional.empty();
    }
    StreamDataOutput streamDataOutput = booleanOutputStream.getStreamDataOutput(columnId);
    // rewrite the DATA stream created by the boolean output stream to a PRESENT stream
    Stream stream = new Stream(columnId, PRESENT, toIntExact(streamDataOutput.size()), streamDataOutput.getStream().isUseVInts());
    return Optional.of(new StreamDataOutput(sliceOutput -> {
        streamDataOutput.writeData(sliceOutput);
