Dataflow 作業在 BigQuery 寫入時失敗並出現后端錯誤

Question

我有一份工作失敗，有幾個與最終導入 BigQuery 相關的不同錯誤。 我已經運行了 5 次，但每次都失敗，盡管錯誤消息有時會有所不同。 當我在本地針對 SQLite 數據庫運行它時，這項工作運行良好，所以我認為問題出在 Google 后端。

一條錯誤信息：

**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.**

有任何想法嗎？ 工作 ID 2019-11-27_09_50_34-1251118406325466877，如果谷歌的任何人正在閱讀這篇文章。 謝謝。

Answer 1

谷歌雲支持在這里。 我檢查了你的工作，我發現了兩個可能與這次失敗有關的內部問題。 正如 Alex Amato 在他的評論中所建議的那樣，我會嘗試使用

--experiments=use_beam_bq_sink

否則，我建議您直接在 GCP 上開票，因為這可能需要進一步調查。

我希望這有幫助。
