Я пытаюсь загрузить json-файл с более чем 100 столбцами в Bigquery.У некоторых из этих столбцов есть специальный символ в их имени, то есть знак доллара ($) и точка (.) Содержание строк / записей также различается - это означает, что не все столбцы могут присутствовать в каждой строке / записи, что является полностью приемлемым форматом json.
У меня есть похожие сообщения
Как управлять / обрабатывать изменения схемы при загрузке файла JSON в таблицу BigQuery
BigQuery: создать столбецтипа данных JSON
, которые предлагают загружать данные в один столбец «STRING» в формате CSV вначале и анализировать столбцы с помощью функции JSON_EXTRACT () для целевой таблицы.Поэтому я создал таблицу BigQuery со следующим определением схемы:
[{"name": "data", "type": "STRING"}]
, затем я выполнил следующую команду CLI:
bq load --source_format = CSV test.bq_load_test ./data_file.json ./bq_load_test_schema.json
, что приводит к следующей ошибке:
Сообщение об ошибке: Ошибка BigQuery в операции загрузки: задание обработки ошибки: ошибка при чтении данных, сообщение об ошибке: таблица CSV обнаружила слишком много ошибок, отказывает.Ряды: 1;Ошибки: 1. Пожалуйста, просмотрите коллекцию ошибок [] для более подробной информации.Сведения об ошибке: - Ошибка при чтении данных, сообщение об ошибке: Слишком много значений в строке, начиная с позиции: 0.
Вот схема файла данных:
