如何将 GCS 嵌套 JSON 放入 BQ 表中

BQ表：

通过下面的架构和命令，我能够加载数据。

您需要定义架构并运行如下

bq load

命令

bq --location=australia-southeast1 load --source_format=NEWLINE_DELIMITED_JSON YOUR_DATASET.PROJECT_ID gs://YOUR_GCS_LOCATION_WHERE_DATA/sample_json_data.json sample_json_schema.json --this is the schema file below on your local directory

[
  {
    "name": "end_location",
    "type": "RECORD",
    "mode": "NULLABLE",
    "fields": [
      {
        "name": "coordinates",
        "type": "FLOAT",
        "mode": "REPEATED"
      },
      {
        "name": "crs",
        "type": "RECORD",
        "mode": "NULLABLE",
        "fields": [
          {
            "name": "properties",
            "type": "RECORD",
            "mode": "NULLABLE",
            "fields": [
              {

                "mode": "NULLABLE"
              }
            ]
          },
          {
