如何使用Apache Beam Python SDK讀取嵌套結構?如何使用Dataflow Python SDK讀取BigQuery嵌套表
lines = p | io.Read(io.BigQuerySource('project:test.beam_in'))
結果
"reason": "invalidQuery",
"message": "Cannot output multiple independently repeated fields at the same time. Found classification_item_distribution and category_cat_name"
是否可以讀取嵌套結構?
謝謝。有趣的是,Java SDK允許沒有任何額外配置的嵌套結構。 –
