示例1: AsyncByteQueue

async function *recordBatchReaders(createSourceStream: () => NodeJS.ReadableStream) {

    let json = new AsyncByteQueue();
    let stream = new AsyncByteQueue();
    let source = createSourceStream();
    let reader: RecordBatchReader | null = null;
    let readers: AsyncIterable<RecordBatchReader> | null = null;
    // tee the input source, just in case it's JSON
    source.on('end', () => [stream, json].forEach((y) => y.close()))
        .on('data', (x) => [stream, json].forEach((y) => y.write(x)))
       .on('error', (e) => [stream, json].forEach((y) => y.abort(e)));

    try {
        for await (reader of RecordBatchReader.readAll(stream)) {
            reader && (yield reader);
        }
        if (reader) return;
    } catch (e) { readers = null; }

    if (!readers) {
        await json.closed;
        if (source instanceof fs.ReadStream) { source.close(); }
        // If the data in the `json` ByteQueue parses to JSON, then assume it's Arrow JSON from a file or stdin
        try {
            for await (reader of RecordBatchReader.readAll(bignumJSONParse(await json.toString()))) {
                reader && (yield reader);
            }
        } catch (e) { readers = null; }
    }
