To avoid exceeding BigQuery's 1500 daily table modification limit,
to_gbqnow prioritizesINSERTorMERGEDMLs. This method is used when the target table exists and shares the same schema, supporting both data replacement and appending. If schema discrepancies are found,to_gbqwill default back to its original table modification process.Fixes internal issue 409086472 🦕
