> Scenario:
> If temp_tables are being used, during copying data from the temp table to the
> destination table, if there is a failure in BigQuery mid-way through
> execution, it will raise an Exception causing the pipeline to fail. As a
> result, some temp_tables will be copied and some will not be. When the
> pipeline is rerun, it will cause the same data to be written to new
> temp_tables and copy jobs will be triggered to copy this data to the
> destination table.
> This will result in duplicate data being written to the BigQuery destination
> table.
