Rui Wang created SPARK-40645:
--------------------------------

             Summary: Throw exception for Collect() and recommend to use toPandas()
                 Key: SPARK-40645
                 URL: https://issues.apache.org/jira/browse/SPARK-40645
             Project: Spark
          Issue Type: Sub-task
          Components: Connect
    Affects Versions: 3.4.0
            Reporter: Rui Wang


Current connect `Collect()` return Pandas DataFrame, which does not match with PySpark DataFrame API: https://github.com/apache/spark/blob/ceb8527413288b4d5c54d3afd76d00c9e26817a1/python/pyspark/sql/connect/data_frame.py#L227.

The underlying implementation has been generating Pandas DataFrame though. In this case, we can choose to use to `toPandas()` and throw exception for `Collect()`.
