  • You cannot create a Google BigQuery target table that contains repeated columns using the
    Create Target
    option.
  • If the Google BigQuery source table contains repeated columns, you cannot configure data filters for these columns.
  • If the Google BigQuery table contains more than one repeated column, you cannot preview data.
  • If the Google BigQuery target table contains repeated columns, you cannot configure update and delete operations for these columns.
  • You cannot configure upsert operations for columns of the Record data type and repeated columns.
  • When you read data from a Google BigQuery source, you must not map more than one repeated column in a single mapping. You must create multiple mappings for each repeated column.
