我正在通过Java API从BigQuery下载一个大型查询结果集。Google BigQuery套接字超时
大约1小时后,底层套接字被关闭,导致SocketException错误,并且查询失败。
如何扩展套接字超时或者最好禁用它? 以下是我建立连接的方式。
InputStream credentialsJSON = new FileInputStream("path.json");
NetHttpTransport transport = new NetHttpTransport();
JsonFactory jsonFactory = new JacksonFactory();
GoogleCredential credential = GoogleCredential.fromStream(credentialsJSON, transport, jsonFactory);
credential.setExpiresInSeconds(null);
// Inject the BigQuery scope if required.
if (credential.createScopedRequired()) {
Collection<String> bigqueryScopes = BigqueryScopes.all();
credential = credential.createScoped(bigqueryScopes);
}
return new Bigquery.Builder(transport, jsonFactory, credential)
.setApplicationName("ETL")
.build();
}
堆栈跟踪
