要确定查询是否已运行完毕，请定期使用 queries.reports.get，然后检查资源的 metadata.status.state 字段已更新为 DONE 或 FAILED。此过程称为“轮询”。

对长时间运行的报告进行低效的轮询实现检查会消耗 API 请求配额较高。为了限制重试次数并节省配额请使用指数退避算法。

下面展示了如何使用指数退避算法轮询报告：

Java

    service.queries().reports().get(queryId, reportId);

// Get initial report object.

        .build();

// Poll report while it is running.
while (!report.getMetadata().getStatus().getState().equals("DONE")
    && !report.getMetadata().getStatus().getState().equals("FAILED")) {
  long backoffMillis = backOff.nextBackOffMillis();
  if (backoffMillis == ExponentialBackOff.STOP) {
    break;
  }
  System.out.printf(
      "Report %s still running, sleeping for %s seconds.%n",
      reportId,
      backoffMillis / 1000);
  Thread.sleep(backoffMillis);

  // Get current status of operation.
  report = reportGetRequest.execute();
}

// Print the result of the report generation.

      report.getKey().getReportId());
