数据流作业在 BigQuery 写入失败并出现后端错误

【中文标题】数据流作业在 BigQuery 写入失败并出现后端错误

【英文标题】：Dataflow job fails at BigQuery write with backend errors

【发布时间】：2019-11-27 19:16:43

【问题描述】：

我的工作因与最终导入 BigQuery 相关的几个不同错误而失败。我已经运行了 5 次，但每次都失败，尽管错误消息有时会有所不同。当我在本地针对 SQLite 数据库运行它时，这项工作运行良好，所以我认为问题出在 Google 后端。

一条错误消息：

**Workflow failed. Causes: S04:write meter_traces_combined to BigQuery/WriteToBigQuery/NativeWrite failed., BigQuery import job "dataflow_job_5111748333716803539" failed., BigQuery creation of import job for table "meter_traces_combined" in dataset "ebce" in project "oeem-ebce-platform" failed., BigQuery execution failed., Unknown error.**

有什么想法吗？职位 ID 2019-11-27_09_50_34-1251118406325466877，如果 Google 的任何人正在阅读此内容。谢谢。

看起来很像***.com/questions/59077063/…

请考虑尝试使用 --experiments=use_beam_bq_sink 这可能会解决问题。否则，您可能需要通过 Google Cloud 支持来解决此问题。

【参考方案1】：

谷歌云支持在这里。我检查了您的工作，发现了两个可能与此故障有关的内部问题。正如 Alex Amato 在他的评论中所建议的那样，我会尝试使用

--experiments=use_beam_bq_sink

否则，我建议您直接在 GCP 上开票，因为这可能需要进一步调查。

希望对你有帮助。
