[英]How to deal with too much nested fields when creating a table on Bigquery
我在 Bigquery 上，我正在嘗試從 Parquet 文件創建一個表。 我收到此錯誤：
Failed to create table: Error while reading data, error message: Field 'produit.elements.bag.array_element.couche_matiere.bag.array_element.composition_coloris.bag.array_element.composition.bag.array_element.libelle_compo.bag.array_element.code_langue' is nested too deeply. It has definition level 17 while maximum allowed definition level is 15.
我知道我有太多 (17) 個嵌套字段，但我必須處理這個模式。
有沒有人知道如何處理這個問題？
謝謝
解決方法是將 parquet 文件轉換為 ORC 格式。
