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; }
